Answer:
Rate of heat transfer will be 10.69 kw
Explanation:
We have given temperature
From standard table enthalpy of vaporization 2382.75 KJ/kg
Steam is coming out from turbine at rate of 16.154 kg/hour
We have to calculate the rate of heat transfer
Heat transfer is equal to
So rate of heat transfer
=
So rate of heat transfer will be 10.69 kw
I do not think that their is energy in space because, everything is floats because of gravity. So it's matter which takes its place and, gravitation !!! Hope this helps
Answer:
a = 0.0505 [m/s^2]
Explanation:
In order to solve this formula we must use the following formula of kinematics.
where:
x = distance = 50000 [m]
Vo = initial velocity = 0
a = acceleration [m/s^2]
t = time = 23 [min] = 1380 [s]
Note: the positive sign in the above equation shows that the car accelerates.
50000 = (0*1380) + (0.5*a*1380^2)
a = 0.0525 [m/s^2]
But we can calculate the acceleration using the following formula:
where:
Vf = final velocity = 67 [m/s]
67 = 0 + (a*1380)
a = 0.0485 [m/s^2]
We can see that by means of kinematics and with the given values we can find two values of accelerations, however, we can determine the average acceleration, by means of the mathematical average.
a = (0.0485 + 0.0525) / 2
a = 0.0505 [m/s^2]
