A 0.10-m-diameter circular cylinder moves through air with a speed U. The pressure distribution on the cylinder's surface is approximated by the three straight-line segments shown in Fig. P9.8. Determine the drag coefficient on the cylinder. Neglect shear forces.
Determine the flowrate per unit width, q, over a broad-crested weir that is 2.0 m tall if the head, H, is 0.50 m.
steam at 1000 f and 1200 psia enters a turbine. the turbine exhausts into a condenser at 4 psia and is 85 efficientb
A reverse Brayton cycle refrigeration system uses air as the working fluid. The turbine and compressor operate ideally, and regeneration (recuperation) is used in the cycle. The pressure ratio is 5. Air enters the compressor at 12.5 psia, 70°F. After..
a rigid tank has a volume of 60 liters and initially contains a two-phase liquid-vapor mixture of h2o at a pressure of
A square gate, 4 m by 4 m, is located on the 45° face of a dam. The top edge of the gate is 8 m below the water surface. Determine the resultant force of the water on the gate, and the point through which it acts.

You have a liquid-phase mixture of 0.250 mol fraction ethanol and 0.750 mol fraction water at 760.0 mmHg. You'd like to calculate the bubble-point temperature of the mixture, and the composition of the vapor formed at the bubble-point temperature. As..
A common approach to system testing is to test the system until the testing budget is exhausted and then deliver the system to customers. Discuss the ethics of this approach for systems that are delivered to external customers.
consider a solid cylinder of radius r and height h. heat is generated in the solid at a uniform rate of q wm3. one of
