a) A fluid is weighed in the lab. It is found that 2.1 U.S. gallons of the fluid weighs 155.2 ounces. What is the fluid’s density in kg/m3? b) A formula to estimate the volume rate of flow, Q, flowing over a dam of length, B, is given by the equation: Q = 3.09BH^(3/2). Where H is the depth of the water above the top of the dam (called the head). This formula gives Q in ft 3 /s when B and H are in feet. Is the constant, 3.09, dimensionless? Would this equation be valid if units other than feet and seconds were used? c) A tank contains 500 kg of a liquid whose specific gravity is 2. Determine the volume of the liquid in the tank.
