Water at 10 ◦C enters a circular pipe of internal diameter 2.5 cm with an average velocity of 1.2 m/s. Steam condenses on the outside of the pipe so as to keep the surface temperature of the pipe at 82 ◦C. If the length of the pipe is 5 m, determine the outlet temperature of water.

Combustion gases passing through a 2.3-cm-internal diameter circular tube are used to vaporize waste water at atmospheric pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean velocity of 5 m/s, and leave at 150°C. If the average heat transfer coefficient is 120 W/m2 °C and the inner surface temperature of the tube is 112°C, determine the tube length. Answer in cm with two(2) decimal places.

A 100-m long horizontal pipe carries water at an average velocity of 2.5 m/s. The required pressure drop, deltaP, across the length of the pipe required to achieve this is 1.5 x 10^5Pa, and the surface roughness to diameter ratio of the inside of the pipe is k/D= 0.004. What is the diameter of the pipe? The only current example on chegg of this problem is wrong.

Liquid water flows in a long pipe of internal diameter of D = 0.01 m at a mean velocity of V = 0.065 m/s. The pipe is maintained at a constant and uniform surface temperature. Assume the flow is both hydrodynamically and thermally fully developed. For simplicity, evaluate the properties of water at 300 K. Calculate the convective heat transfer coefficient of the flow inside the pipe in W/m2K?
