Questions from Thermal Fluid Science

Q: Repeat Prob. 9–95 for a heat rejection pressure of

Repeat Prob. 9–95 for a heat rejection pressure of 10 kPa. Data from Prob. 9-95: A steady-flow Carnot cycle uses water as the working fluid. Water changes from saturated liquid to saturated vapor as...

Q: Consider a steady-flow Carnot cycle with water as the working

Consider a steady-flow Carnot cycle with water as the working fluid. The maximum and minimum temperatures in the cycle are 350 and 60°C, respectively. The quality of water is 0.891 at the beginning of...

Q: Water enters the boiler of a steady-flow Carnot engine as

Water enters the boiler of a steady-flow Carnot engine as a saturated liquid at 300 psia and leaves with a quality of 0.95. Steam leaves the turbine at a pressure of 20 psia. Show the cycle on a T-s d...

Q: Define the resultant hydrostatic force acting on a submerged surface, and

Define the resultant hydrostatic force acting on a submerged surface, and the center of pressure.

Q: Consider an 8-m-long, 8-m-

Consider an 8-m-long, 8-m-wide, and 2-m-high above ground swimming pool that is filled with water to the rim. (a) Determine the hydrostatic force on each wall and the distance of the line of action of...

Q: Consider a heavy car submerged in water in a lake with a

Consider a heavy car submerged in water in a lake with a flat bottom. The driver’s side door of the car is 1.1 m high and 0.9 m wide, and the top edge of the door is 10 m below the water surface. Dete...

Q: A room in the lower level of a cruise ship has a

A room in the lower level of a cruise ship has a 40-cm-diameter circular window. If the midpoint of the window is 2 m below the water surface, determine the hydrostatic force acting on the window, and...

Q: The water side of the wall of a 70-m-

The water side of the wall of a 70-m-long dam is a quarter circle with a radius of 7 m. Determine the hydrostatic force on the dam and its line of action when the dam is filled to the rim.

Q: A water trough of semicircular cross section of radius 0.6

A water trough of semicircular cross section of radius 0.6 m consists of two symmetric parts hinged to each other at the bottom, as shown in Fig. P11–14. The two parts are held toget...
