Water in a piston-cylinder assembly, initially at a temperature of 99.63°C and a quality of 65%, is heated at constant pressure to a temperature of 200°C. If the work during the process is 1300 kJ, determine
(a) the mass of water, in kg, and
(b) the heat transfer, in kJ. Changes in kinetic and potential energy are negligible.
The panel shown forms the end of a trough that is filled with water to the line AA9. Referring to Sec. 9.2, determine the depth of the point of application of the resultant of the hydrostatic forces acting on the panel (the center of pressure).
The virial equation of state for n-butane at 460K is Z=1+A/V+B/V^2 in which A =-265 cm^3/g and B= 30250 cm^6/(g*mole^2). Calculate the work required to reversibly compress one mole of n-butnae from 50 atm to 100 atm at 460K
