Avertical 12-cm diameter piston-cylinder device contains an ideal gas at the ambient conditions of 1 bar and 24 degrees c. initially, the inner face of the piston is 20 cmfrom the base of the cylinder. now an external shaft connected to the piston exerts a force corresponding to a boundry work input of 0.1 kj. the temperature of the gas remains constant during the process. determine
(a) the amount of heat transfer,
(b) the final pressure in the cylinder, and
(c) the distance that the piston is displaced.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

What precautions should you take to prevent injuries when dealing with heavy loads?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
