Water 100C flows across a bank of tubes 15 rows high and 6 rows deep (in the flow direction) at a velocity of 6.5 m/s measured at a point in the flow before the air enters the tube bank. The surfaces of the tubes are maintained at 40C. The diameter of the tubes is 2.50 cm; they are arranged in an in-line manner so that the spacing in both the normal and parallel directions to the flow is 4.0 cm.

(a) Heat transfer coefficient,

(b) Fluid exit temperature,

(c) Log mean temperature difference,

(d) Rate of heat transfer
