Explanation:
Equation for energy balance will be as follows.
Hence,
Therefore, we will calculate the final temperature as follows.
= 868.03 R
Now, we will calculate the mass as follows.
m =
=
= 1.031 lbm
Hence,
Putting the values into the above equation as follows.
= 655.2 Btu
Thus, we can conclude that work done by paddle wheel is 655.2 Btu.
The scale in N, reading if the elevator moves upward at a constant speed of 1.5 m/s^2 is 862.5 N.
weight of man = 75kg
speed of elevator, a = 1.5
So, the scale reading in the elevator is greater than his 862.5 N weight. This indicates that the person is being propelled upward by the scale, which it must do in order to do so, with a force larger than his weight. According to what you experience in quickly accelerating or slowly moving elevators, it is obvious that the faster the elevator acceleration, the greater the scale reading.
Speed can be defines as the pace at which the position of an object changes in any direction. Since speed simply has a direction and no magnitude, it is a scalar quantity.
