Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

If the mass of an object is 10 lbm, what is its weight, in lbf, at a location where g = 32.0 ft/s2 ?
* Your answer is incorrect. A piston-cylinder assembly contains 0.7 lb of propane. The propane expands from an initial state where p₁ = 60 lbf/in.² and T₁ = 70°F to a final state where p₂ = 10 lbf/in.² During the process, the pressure and specific volume are related by pv² = constant. Determine the energy transfer by work, in Btu. W = i 3.123 Btu
Work is done on an adiabatic system due to which its velocity changes from 10 m/s to 20 m/ s. elevation increases by 20 m and temperature increases by 1 K. The mass of the system is 10 kg. Cv= 100 J/(kg K) and gravitational acceleration is 10 m/s². If there is no change in any other component of the energy of the system, the magnitude of total work done (in kJ) on the system is
3. The internal energy of a certain substance is given by the following equation: u = 3.56 pv + 84 where u is given in kJ/kg ; p is in kPa and v is in m³/kg. A system composed of 3 kg of this substance expands from an initial pressure of 500 kPa and a volume of 0.22 m' to a final pressure of 100 kPa in a process in which pressure and volume are related by pv¹2 = constant. If the expansion is quasi-static, find the internal energy and the heat transfer during the process.
A construction crane weighing 12,000 lbf fell from a height of 500 ft to the street below during a severe storm. For g = 32.05 ft/s², determine the mass, in lb, and the change in gravitational potential energy of the crane, in ft-lbf.
The pressure from water mains located at street level may be insufficient for delivering water to the upper floors of tall buildings. In such a case, water may be pumped up to a tank that feeds water to the building by gravity. For an open storage tank atop a 300-ft-tall building, determine the pressure, in lbf/in² , at the bottom of the tank when filled to a depth of 20 ft. The density of water is 62.2 lb/ft³, g = 32.0 ft/s2 , and the local atmospheric pressure is 14.7 lbf/in²
