1. A tank that is vented to the atmosphere holds crude oil for a large petroleum company on the Texas gulf coast. The height of the oil in the tank is H. The tank is surrounded by a dike that is of a height of 0.5H.
A. Find the absolute pressure in the tank in psia if H= 15 ft.
B. Find the absolute pressure in the tank in Pa if H= 5 m.
C. Explain what the dike is used for.
SG of the oil is 0.846
2. Water is flowing at 100 lbm / s in a circular drain pipe of 1 m in diameter. This 1 meter diameter pipe comes to an abrupt constriction when the diameter suddenly reduces to 1.5 feet.
A. Find the volumetric flow rate through both pipes in m3 / hr.
B. Find the velocity of the water in both pipes in m/s.
Density of water = 1 g/ml
