Apressure gage and a manometer are connected to a compressed air tank to measure its pressure. if the reading on the pressure gage is 11 kpa, determine the distance h between the two fluid levels of the water filled manometer. assume the density of water is 1000 kg/m3 and the atmospheric pressure is 101 kpa. quiz 3

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

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

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
