Water at 15°C is to be heated to 65°C by passing it over a bank of resistance heating rods 4 m long and 1 cm in diameter which are maintained at 90°C. The water is approached by the heater rod bank at the normal direction at an average speed of 0.8 m/s. The rods are arranged in line with longitudinal and transverse steps of SL = 4 cm and ST = 3 cm. Determine the number of rows of NL tubes in the direction of flow needed to achieve the indicated temperature rise. I need the solution from fundamental concepts of how the heat flow behaves in the system
