Water enters a pump steadily at 100 kPa at a rate of 35 L/s and leaves at 800 kPa. The flow velocities at the inlet and the exit are the same
Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kW of shaft power
Water in a piston/cylinder is at 1 MPa, 500°C. There are two stops, a lower one at which Vmin = 1 m3 and an upper one at Vmax=3 m3.
Water is boiling at 1 atm pressure in a stainless steel pan on an electric range. It is observed that 2 kg of liquid water evaporates in 30 min.
Water is boiled in a pan on a stove at sea level. During 10 min of boiling, it is observed that 200 g of water has evaporated.
Water is boiled at 1 atm pressure in a 25-cm-internaldiameter stainless steel pan on an electric range.
Water in a piston/cylinder is at 90°C, 100 kPa, and the piston loading is such that pressure is proportional to volume, P =CV
Water as saturated liquid at 200 kPa goes through a constant pressure heat exchanger. The heat input is supplied from a reversible heat pump
Warm air is contained in a piston-cylinder assembly oriented horizontally as shown in Fig.
Water at 50°F and 50 psia is heated in a chamber by mixing it with saturated water vapor at 50 psia
Water at 1000 kPa, 250°C is brought to saturated vapor in a piston/cylinder with an isothermal process. Find the specific work and heat transfer
Underground water is being pumped into a pool whose cross section is 3 m 4 m while water is discharged through a 5-cm-diameter orifice at a constant average

Two tanks are connected both containing water. Tank A is at 200 kPa, v = 0.5 m3/kg, VA= 1 m3 and tank B contains 3.5 kg at 0.5 MPa, 400°C.
Two flows of air both at 200 kPa of equal flow rates mix in an insulated mixing chamber. One flow is at 1500 K and the other is at 300 K.
The valve is now opened, and the two tanks eventually come to the same state. Determine the pressure and the amount of heat transfer when the system reaches
Two rigid tanks are connected by a valve. Tank A is insulated and contains 0.2 m3 of steam at 400 kPa and 80 percent quality
Two hydraulic piston/cylinders are connected through a hydraulic line so they have roughly the same pressure. If they have diameters of D1 and D2 = 2D1
f 25 J is the work input to the master cylinder what is the force and displacement of each piston and the work out put of the slave cylinder piston?
Two hydraulic piston/cylinders are connected with a line. The master cylinder has an area of 5 cm2 creating a pressure of 1000 kPa.
Two heavily insulated tanks are connected by a valve. Tank A contains 0.6 kg of water at 300 kPa 300?C. Tank B has a volume of 300 L and contains water
