Let's understand the average power calculation of any vehicle.
This is the very state calculation.
Average power calculation is average power required to achieve that acceleration rate acceleration rate
is time required to attain a certain speed and all vehicle has that been paid mass?
So we apply the simple projects and by calculating the work done and rhomberg then will calculate the
power.
So physically the vehicle is the mass and continued the weight of the vehicle as a 150 KAIJI.
So because we are having the wheel arrangement, frictional losses, friction is very limited and due
to the very small amount of force required to accelerate it.
But we are not currently interested in force and dynamic equation, but we are only interested in calculating
the average power calculation that will depend upon math as well as the acceleration rate.
We know that that is one of the performance barometer of any vehicle.
We must help exclusion rate.
Let's follow the example we consider it's near, and second, to read the velocity of five meters per
second notice given in meters per second.
What is the calculation here?
And waited 150 Kaiji.
So is 150 cagy and a certain distance.
But we are not interested in distance yet.
What we are interested in, how much rising the velocity.
So from the zero to five meters per second is the increase in velocity and it's take the 10 seconds.
So we know that it is the acceleration rate then required to accelerate up to five meters per second
speed so we can attain the speed of five meters per second from zero in 10 seconds.
So we.
Apply the physics math of 150 takes 10 seconds to read of five meters per second, M is equal to 150
math.
We can see that the velocity five meters per second and is d the quarter and second that we can calculate
the well done and then work, then do it by the time will be our power average power.
So what then is that equation one half and V squared.
So M is the mass of Wakan 150 to in our case we is the velocity five meters per second.
So it must be a meter per second and it must be cagy.
They'll put the value of mass and velocity and time in this equation, I would be what then went up
and the script went back.
So if Mass have been cagy relative to 15 meters per second time, must mean second, then our final
unit will become, what, ten meters per second?
So when what is equal to one Newton per second or if to the unit of energy was then what, in two seconds
when we got into intersection is equal to one Newton meter.
So we put the value of m the square and time.
So average power will calculate for the 150 K debate and this acceleration rate, it will become one
eighty seven point five one.
So this much mechanical minimum mechanical power is required to attain this acceleration rate for this
mass.
So we know the basic parameters of vehicle that is mass, basic performance parameter, acceleration
rate of vehicle, and we can calculate the average power.
Now, if in case of electric vehicle, the motor is supplying this power.
So rating our rating of the motor must be higher than the one eighty five point seven what.
So next higher our level rating of the motor that is available in market that can be used for this to
achieve this performance.
Select next higher rating motor from the available variant.
And that is 125 watt of electric motor.
If it is if it is a vehicle, then engine power is required.
Output engine power must be higher than this to achieve this performance even.
But this is a model output part of the world and electrical input.
Motor power will be higher than this depending upon its efficiency losses.
Take one more case now, we consider the 12, 13 kilometers per hour instead of meters per second,
so we need to convert in meter per second.
Part of the calculation in is 150 KAIJI.
It's take 10 seconds to reach velocity of 30 kilometers per hour.
So acceleration rate is given, is given.
So M is equal to 150.
Let's convert velocity from kilometer per hour to the meter per second.
So 30 from the kilometer, one kilometer cycle, two thousand meter one are ridiculous and each minute
is equal to 60 seconds.
So by applying this will have the eight point three three meters per second velocity at 30 kilometers
per hour speed.
It is eight point three meters per second and time is 10 seconds.
Let's calculate down at about one up and the square, Betty, and putting this all together, we will
have average power output is equal to twenty point eighty three.
What that means.
It puts the electric vehicle very quite the motor power output, motor power higher than this one.
So next higher is the 600 what model that means to achieve this execution date for this mass of the
vehicle, we require the 600 watt electric motor.
This is state calculation.
We will see the dynamic calculation also for modeling, but the simple calculation can be helpful in
some case.
OK, you understand what the average power calculation of an.
Time to exercise and train your mind, let's find out the time required for 20, 30 months to read the
velocity of 50 km at 1:00 a.m., yet the power of motors given.
You need to calculate the acceleration rate.
So find out the time and calculate acceleration rate and share your answer with your remarks in comments
section.
