question

A 1(1/2) in sch. 40 steam pipe is laid in the atmosphere where the temperature is 50°F. The steam inside it is saturated at 100psia. Consider the pipe to be a grey body anduninsulated. The coefficient of heat transfer by natural convection from the outside surface is 2.0 Btu/hr sq ft R. Calculate the amount of steam con-densed per hour per unit length of pipe.
