In a horizontal condenser, an arrangement of 8 rows of horizontal tubes with 9 tubes each row (columns) having an outside diameter of 5 cm and a length of 7 m each tube is used. Saturated water vapor at 101.3 kPa condenses on the outer surface of the tubes, which is maintained at a temperature of 80C. Calculate the condensation rate of the water vapor in the steady state, in kg/h with two decimal places. Consider the film temperature as a linear average
