Question: 1- A steel pipe with outer diameter D = 0.2 m is used to transmit steam in an outdoor environment. Wind is blowing perpendicular

1- A steel pipe with outer diameter D = 0.2 m is used to transmit steam in an outdoor environment. Wind is blowing perpendicular to the pipe axis with velocity of V = 10 m/s. If the wind temperature is of T.. = 40 C and surface temperature of the pipe is Ts 80 C, find: = a) Average convection coefficient of pipe, h. (7 points) b) Heat transfer rate (from pipe to air) per unit length of the pipe. (3 points). V D
