There is a bundle of tubes with a staggered arrangement, with 15 transverse tubes and 6 flow direction rows, the diameter of the tubes is 1 inch, air flows at 1.2 atm and 10C, the longitudinal and transverse separation are 3.81 cm and 4.5 cm respectively. If the flow velocity is m/s measured at the inlet of the tube bundle. The temperature on the surface of the tubes is d Estimating the properties of the fluid as a function of the average temperature, evaluated

inlet temperature and surface temperature, determine:

A) The total heat transferred
