A 0.06-lb bullet is fired with a horizontal velocity into the lower end of a 45-lb slender bar which is initially at rest in a vertical plane
You drive a car on a winter day with the atmospheric air at -15°C and you keep the outside front windshield surface temperature
Determine by direct integration the polar moment of inertia of the area shown with respect to point O.
When the transportation of natural gas in a pipeline is not feasible for economic reasons, it is first liquefied using non-conventional refrigeration techniques
When a man returns to his well-sealed house on a summer day, he finds that the house is at 32°C.
Water is used as the working fluid in a Carnot cycle heat engine, where it changes from saturated liquid to saturated vapor at 200°C as heat is added
Water enters the boiler of a steady-flow Carnot engine as a saturated liquid at 180 psia and leaves with a quality of 0.90.
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 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 1.5 MPa, 150°C, is throttled adiabatically through a valve to 200 kPa. The inlet velocity is 5 m/s, and the inlet and exit pipe diameters are the same.
