Technician A states that once the thermostat has been removed, one should clean any old gasket material and corrosion that has built up on both sealing surfaces where the thermostat seats. Technician B states that it is fine to let a faulty thermostat run till it completely breaks down. Who is correct

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.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
