A frictionless piston-cylinder system contains 10kg of water at 20C at atmospheric pressure. An external force F is then applied on the piston until the pressure inside the cylinder increases to 100atm. assuming the coefficient of compressibility of water remains unchanged during compression, estimate the energy needed to compress the water isothermally. Answer: 29.4 J
At a temperature of 21°C, a cold-rolled red brass [alpha B = 17.6 x 10-6/°C] sleeve has an inside diameter of dB = 314.70 mm and an outside diameter of DB = 325 mm. The sleeve is to be placed on a steel [alpha S = 11.9 x 10-6/°C] shaft with an outsid..
