Answer:
h=12.41m
Explanation:
N=392
r=0.6m
w=24 rad/s
So the weight of the wheel is the force N divide on the gravity and also can find momentum of inertia to determine the kinetic energy at motion
moment of inertia
Kinetic energy of the rotation motion
Kinetic energy translational
Total kinetic energy
Now the work done by the friction is acting at the motion so the kinetic energy and the work of motion give the potential work so there we can find height
Answer:
The heat loss per unit length is
Explanation:
From the question we are told that
The outer diameter of the pipe is
The thickness is
The temperature of water is
The outside air temperature is
The water side heat transfer coefficient is
The heat transfer coefficient is
The heat lost per unit length is mathematically represented as
Substituting values
