Question

Water at a bulk temperature of 21°K flows inside a long hot pipe of constant temperature having a 1.69 cm inside diameter and at a velocity of 13 m/s. Assume the water properties are: • v = 1.003 × 10^-3 m^2/s - k= 613 × 10^-3 W/m-K • Pr = 7 Note that (Nu)bar = (h)barD/k What is the heat transfer coefficient in W/m^2K?

Step 1

- The water flows inside a hot pipe with an inside diameter (D) of 1.69 cm or 0.0169 m. - The velocity of water (V) is 13 m/s. - The kinematic viscosity (v) is 1.003 × 10^-3 m^2/s. - The thermal conductivity (k) is 613 × 10^-3 W/m-K or 0.613 W/m-K. - The Prandtl Show more…
