Rework Problem 20.51 for a staggered arrangement.

Problem 20.51

A tube bank employs an in-line arrangement with
 and tubes that are 1.8 cm in outside diameter. There are 10 rows of tubes, which are held at a surface temperature of 85C. Air at atmospheric pressure and 20C flows normal to the tubes with a free stream velocity of 6 m/s. The tube bank is 10 rows deep, and the tubes are 1.8 m long. Determine the amount of heat transferred.
