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.

** Please label the question answers so I could understand it better! Thank you! Scenario: A chair with a mass of 20.0 kg is attached to one end of a frictionless pulley system via a strong massless rope. The other end of the rope is attached to a steel water tank sitting on a flat horizontal concrete surface (see the image to the right). The coefficient of static friction between steel and concrete is 0.45 and the coefficient of kinetic friction between the surfaces is 0.30. The water tank, which is full of water, has sprung a leak. The combined mass of the water and the tank is 500 kg. This mass slowly decreases as the water leaks from the hole. You (i.e. your entire mass) are sitting at rest in the seat. You and the seat will remain at rest as long as the force of static friction is strong enough to hold you. Task: LET [DOWN] and [RIGHT] be positive. Using your knowledge of physics, determine the following: 1. As soon as the chair begins to move, static friction between the steel…

An electric elevator with a motor at the top has a multistrand cable weighing 8.4 lb/ft. When the car is on the first floor 270 feet of cable are paid out, and effectively 0 feet when the car is on the top floor.

The volumetric efficiency of a certain piston pump is 97%. If the pump delivers 14 L/min at 1200 rpm, find the Volumetric displacement of the pump. A system requires a pump to deliver 30 gal/min at 1500 lbf/in2 at an engine speed of 2000 rpm. calculate theoretical pump displacement, engine torque to drive the unit, and horsepower. A piston pump operating at 1,150 rpm and 3000 Ibf/in2 delivers fluid at 10 gal/min. If the pump has an overall efficiency of 94%. What is the input torque from the driving unit? A pump operating at 2,000 Ibf/in? and delivering 5 gal/min requires 7 bhp to drive the input shaft. Compute the overall efficiency of the pump.
