Question # 73 Air flows through a 10 cm internal diameter tube at the rate of 75 kg/hr. Measurements indicate that at a particular point in the tube, the pressure and temperature of air are 1.5 bar and 325 K whilst the tube wall temperature is 375 K. Find heat transfer rate from one meter length in the region of this point. The general non-dimensional correlation for turbulent flow in the tube is Nu = 0.023 (Re) 0.8 (Pr) 0.4, Where the fluid properties are evaluated at the bulk temperature A. 147.35 W B. 157.35 W C. 167.35 W D. 177.35 W D​
