Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
Question
![A pipe of 25 mm outer diameter carries steam.
The heat transfer coefficient between the cylinder
and surroundings is 5 W/m2K. It is proposed to
reduce the heat loss from the pipe by adding
insulation having a thermal conductivity of 0.05
W/mK. Which one of the following statements is
TRUE?
(a) The outer radius of the pipe is equal to the
critical radius.
(b) The outer radius of the pipe is less than the
critical radius.
(c) Adding the insulation will reduce the heat loss.
(d) Adding the insulation will increase the heat
loss.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa52f8485-baba-4cd6-b8a8-69cc560cb55e%2F4ece5d04-2120-4da2-9616-0d95837128ca%2Fz26zxwc_processed.jpeg&w=3840&q=75)
