Repeat Problem 7.94, but with N L = 7, N T = 10, and V = 10.5

Question:

Repeat Problem 7.94, but with N= 7, N= 10, and V = 10.5 m/s.


Data From Problem 7.94

A tube bank uses an aligned arrangement of 30-mmdiameter  tubes with ST = S= 60 mm and a tube length  of 1 m. There are 10 tube rows in the flow direction  (NL = 10) and 7 tubes per row (N= 7). Air with  upstream conditions of T∞ = 27°C and V = 15 m/s is  in cross flow over the tubes, while a tube wall temperature  of 100°C is maintained by steam condensation  inside the tubes. Determine the temperature of air leaving  the tube bank, the pressure drop across the bank,  and the fan power requirement.
