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
Time required : 3 s
<h3>Further explanation
</h3>
Power is the work done/second.
To do 33 J of work with 11 W of power
P = 11 W
W = 33 J
<span>Velocity is a vector and it has both speed and direction. It takes a force to change direction just as it does to change speed</span>. In order to have a constant velocity the object must maintain a constant direction and speed. Hope this answers the questions. Have a nice day.
