1 00:00:00,990 --> 00:00:05,640 Let's understand the power of iteration and its application. 2 00:00:09,200 --> 00:00:16,550 Did the racial epithet be a vehicle to the total weight of to weaken our capacity is the capacity of 3 00:00:16,820 --> 00:00:17,900 its power source. 4 00:00:18,300 --> 00:00:21,560 That is, I think, are the electric motor. 5 00:00:24,320 --> 00:00:29,300 So to understand the importance of arbitration issue and how it's better with the different condition, 6 00:00:29,540 --> 00:00:31,970 let us consider the case of. 7 00:00:33,990 --> 00:00:38,430 We are already discussing the average particle collision, if we are having the one vehicle, we are 8 00:00:38,430 --> 00:00:46,470 not specifying currently the type of vehicle, but just because we already calculated the power required 9 00:00:46,800 --> 00:00:48,980 for the weight of 150 k.g. 10 00:00:49,440 --> 00:00:57,300 So this power is for the particular performance that we call the acceleration rate and second, to rate 11 00:00:57,300 --> 00:00:59,890 the velocity of 30 kilometers per hour. 12 00:01:00,240 --> 00:01:05,600 So to achieve this performance, average power is required. 13 00:01:05,640 --> 00:01:07,100 Six hundred one. 14 00:01:08,130 --> 00:01:15,840 So we are considering this is the motor power or engine power, whatever you can consider our capacity 15 00:01:16,590 --> 00:01:18,560 and wait, it's 150 k.g. 16 00:01:18,900 --> 00:01:24,180 So when you divide power by weight, what cagy? 17 00:01:26,080 --> 00:01:34,350 The number comes to the fourth of body weight ratio of this weekly, it is very less so. 18 00:01:34,630 --> 00:01:42,060 We'll consider one more case to understand how it's very let's consider the gap year. 19 00:01:42,220 --> 00:01:45,160 We are considering the high performance car. 20 00:01:45,160 --> 00:01:47,440 That means acceleration will be high. 21 00:01:48,400 --> 00:01:52,340 The general weight of the car will be one point five. 22 00:01:52,340 --> 00:01:53,130 Turn around. 23 00:01:55,180 --> 00:02:04,810 You can consider other ways also that I am considering the thousand cagy and I'm considering the performance 24 00:02:04,820 --> 00:02:10,450 that is high performance acceleration that is required six seconds to reach the velocity of hundred 25 00:02:10,450 --> 00:02:11,400 kilometers per hour. 26 00:02:11,770 --> 00:02:15,610 That means very fast acceleration is required. 27 00:02:15,610 --> 00:02:22,190 And for you, this will require the minimum of sixty five km. 28 00:02:22,270 --> 00:02:23,680 What that is lower. 29 00:02:24,370 --> 00:02:25,570 Sixty five thousand. 30 00:02:27,340 --> 00:02:28,750 So this is engine power. 31 00:02:30,520 --> 00:02:34,840 And this is the weight of the God weight of the week. 32 00:02:35,650 --> 00:02:42,190 Remember, the power will depend upon the acquisition factor that Felician higher power will be required. 33 00:02:43,030 --> 00:02:45,000 So they will decide the power. 34 00:02:45,250 --> 00:02:49,880 And so that power efficient will also depend upon the acquisition they had that. 35 00:02:51,430 --> 00:02:53,920 With the power to do the part of it. 36 00:02:55,600 --> 00:02:57,100 Let's calculate for this. 37 00:02:57,110 --> 00:03:06,400 It's gone to the sixty five is the high weight ratio because performance is high now considered the 38 00:03:06,400 --> 00:03:14,700 one more case of the God with the life performance, a low performance, having the same weight of a 39 00:03:14,700 --> 00:03:15,760 thousand k.g. 40 00:03:17,800 --> 00:03:21,910 So in case three, we are closer to the God with the same weight. 41 00:03:22,360 --> 00:03:29,950 But because we are confident exhalations it less that Mr. Ten Seconds required to read the velocity 42 00:03:29,950 --> 00:03:31,000 of 80 km. 43 00:03:31,020 --> 00:03:38,590 But so we compared to previous case yet requirement of performance performance requirement is slightly 44 00:03:38,590 --> 00:03:38,980 less. 45 00:03:39,370 --> 00:03:48,460 So when you calculate the power company less it is twenty five kilowatt of water, power or engine power 46 00:03:48,460 --> 00:03:51,940 is required to achieve this performance for this way. 47 00:03:52,440 --> 00:03:58,930 So now in this case, in this car, weight is same, but our requirement is less. 48 00:03:59,350 --> 00:04:05,150 And power source twenty five kilowatt bodyweight crystal come to twenty five. 49 00:04:06,850 --> 00:04:15,730 This is the typical value, not the actual value of any car, but for to understand how far it is to 50 00:04:15,750 --> 00:04:18,070 change and how would depend upon the acquisition. 51 00:04:18,940 --> 00:04:23,950 So we can see how the power weight ratio models exhibition of weight. 52 00:04:30,110 --> 00:04:38,120 So it does not mean the power of bus will be high, the high rate in high poverty, but a solution is 53 00:04:38,120 --> 00:04:38,420 less. 54 00:04:38,420 --> 00:04:49,160 And if our shoppers will be less than the Garlett cost the one bus yet again, I'm using the one typical 55 00:04:49,160 --> 00:04:53,100 Velu 10000 cagy 10000 Kaiji. 56 00:04:53,420 --> 00:05:02,930 If you consider that then a passenger bus wait very around the approximate done so you can consider 57 00:05:02,930 --> 00:05:06,720 the 2010 110 as their and nine 07 Kaiji. 58 00:05:07,520 --> 00:05:10,220 But for the simplicity I'm using the wrong figure. 59 00:05:10,520 --> 00:05:19,300 One bus and a passenger bus and waitress 10000 Gidgee and I am considering the performance of this bus. 60 00:05:19,310 --> 00:05:23,830 It will take 10 seconds to reach the speed of 60 kilometers. 61 00:05:23,840 --> 00:05:32,990 But I so this is a fair enough performance for the bus and so that it will require the power one thirty 62 00:05:33,260 --> 00:05:39,320 eight kilowatt of engine power or whatever the power source we use. 63 00:05:41,400 --> 00:05:47,010 So if we calculate the borrowing ratio for this month, it will be thirteen point eight. 64 00:05:47,400 --> 00:05:54,730 You can compare it with the previous altricial high performance car, which was 65. 65 00:05:55,140 --> 00:05:56,850 And here are the math. 66 00:05:56,850 --> 00:05:58,920 It is thirteen point eight. 67 00:06:01,610 --> 00:06:13,130 Let's take one more case of bus with the higher weight, every bus, so it is 30000 cagy and the fate 68 00:06:13,130 --> 00:06:21,470 of the performers, it takes 12 seconds to reach the velocity or to you develop to 70 kilometers, but 69 00:06:22,610 --> 00:06:25,760 it takes 12 seconds to return to to the and center. 70 00:06:26,840 --> 00:06:31,310 And if you calculate the power, it comes before seven to one. 71 00:06:32,150 --> 00:06:39,890 So for this power for 32 kilowatt, if we calculate the power to ecclesia, it is still very low. 72 00:06:40,100 --> 00:06:41,930 Fifteen point seven one. 73 00:06:43,940 --> 00:06:46,990 So at last we calculate the ratio of bike. 74 00:06:47,450 --> 00:06:53,490 Let's consider the bike, which is always having the ability to have that with motorcycle. 75 00:06:53,510 --> 00:07:01,150 We consider them a motorcycle with the 250 CGY weight and higher performance. 76 00:07:01,160 --> 00:07:09,050 And in terms of acceleration, acceleration rate is six secon require to rate the speed of 80 kilometers 77 00:07:09,050 --> 00:07:09,240 per. 78 00:07:10,820 --> 00:07:14,510 So for this performance, power requires 10 kilowatts. 79 00:07:14,510 --> 00:07:25,520 So we are having 10 kilowatts of energy or electric motor or the 250 Kaiji motorcycle or bike and bodyweight 80 00:07:25,520 --> 00:07:27,260 ratio will come to 40. 81 00:07:28,160 --> 00:07:32,580 This is also a high powered racer, even with to buzz. 82 00:07:33,740 --> 00:07:37,930 So this is how power weight ratio is calculated and represented. 83 00:07:38,240 --> 00:07:43,310 And in next session we will use the power of education to select the driving cycle and experiment. 84 00:07:43,760 --> 00:07:52,760 And for the safety and efficiency is also so outrageous, the important parameter of the week.
