Steam enters a steam turbine at a volumetric flow rate of 110 ft3/s. The enthalpy of the steam is 1320 Btu/lbm, and the specific volume of the steam is 2.43 ft3/lbm. The velocity of the steam as it enters the steam turbine is 250 ft/s, and the height of the entrance above the ground is 10 ft. The acceleration due to gravity is 32.17 ft/s2. Determine the rate at which energy is being transferred via mass flow for the steam.
Given: V?= 110 ft3/s; h = 1320 Btu/lbm; v = 2.43 ft3/lbm; V = 250 ft/s; z = 10 ft; g = 32.17 ft/s2 What will be an ideal response?
Assume that the data shown in Table 4.2 were collected on a rural road in your state and consideration is being made to set the speed limit on the road. Speed limits of 50, 55, 60, and 65 mi/h are being considered. Plot the expected non-compliance percentages vs. the associated speed limit on a graph and recommend the speed for the road. Give reasons for your selection.
