Solution of Test 1 for Thermodynamics I (Dr . He) 1 Gasoline pressure is determined Assumptions 1 All the liquids are incompressible and immiscible. 2 The effect of air column on pressure is negligible. Properties The specific gravities of oil, mercury, and gasoline are given to be 0.79, 13.6, and 0.70, respectively. We take the density of water to be ρ w = 1000 kg/m3. Analysis Starting with the pressure indicated by the pressure gage (known as reference) and moving along the tube (label 1, 2, 3, 4) by adding (as we go down) or subtracting (as we go up) the ρ gh terms until we reach the gasoline pipe, and setting the result equal to P gasoline gives Rearranging, Substituting, 2 The available head, flow rate, and efficiency of a hydroelectric turbine are given. The electric power output is to be determined.
