(a) Kerosene at 40C flows through a 0.3m diameter line in a refinery. The flow rate is expected to be 90-120 kg/s. A manometer with water as a manometer fluid with maximum possible deflection of 1m is available for use with a square edged orifice meter. Specify a recommended orifice diameter for use with this system. Specific gravity and viscosity of kerosene at 40C are 0.82 and 1X103N.s/m2. Discharge coefficient for the orifice meter =0.61. (b) A cylindrical tank of diameter 50mm drains through a 5mm diameter opening in the bottom of the tank. The speed of the liquid leaving the tank is approximately V=2gy, where y is the height from the tank bottom to the free surface. If the tank is initially filled with water to 0.4m, find the water depth at r=12 s. 8+8
