1. A lead pipe has 2 cm inside diameter, 3 cm outer diameter, length of 130 cm. Liquid water at 4°C flows through the pipe with a bulk velocity of 2.50 km/hr. Air is blown around the outside of the pipe at 20 deg C. The inside wall of the said pipe has a temperature of 8 deg Celsius. Find: Overall heat coefficient (U) based on outside surface area b. Prandtl (Pr) and Reynolds (Re) numbers based on classification of flow а.
