Step 1

The surface area can be calculated using the formula for the surface area of a cylinder: Surface Area = 2πrh + 2πr^2 where r is the radius of the pipe and h is the length of the pipe. Given that the inner diameter of the pipe is 4 cm, the radius is half of Show more…

A 15 m long pipe (k=52) in the basement with hot water at 90 degrees Celsius and a speed of 1.2 m/s. The inner diameter of the pipe is 4 cm, the outer diameter is 4.6 cm, and the emissivity is 0.7. The outside and basement wall temperatures are both 10 degrees Celsius, and the outside of the pipe has a heat transfer coefficient of 12 W/mK. (a) Find the heat loss rate of water. (b) What is the temperature of the leaving hot water? Tambient = 10°C.
