1. GUANZHO Bus Manufacturer install a ventilating fan in each bus with a suction duct diameter 0.315 m and discharge duct of 0.285 m diameter. A design air flow of 2.50 m³ per second passes through the system with a static pressure head of 1.85 cm of water column WC as air measured at 21 °C. Solve the hs = static head, hv= velocity head and the hT = total head of the ventilating fan. 2. A second Fan similar to that of problem 1 was installed in a mini bus assembled by GUANZHO Bus Mnftg Co. with the following data: Q = 2.25 m³ per second N = 675 rpm Compute the rpm of the fan in the Bus at problem 1 and the total head of the second fan.
