- A fluid is contained in a cylinder by a spring-loaded, frictionless piston so that the pressure in the fluid is linear function of the volume (p = a + bV). The internal energy of the fluid is given by the following equation U = 34 + 3.15 pVwhere U is in kJ, p in kPa and V in cubic metre. If the fluid changes from an initial state of 173 kPa, 0.03 m3to a final state of 400 kPa, 0.06 m3, with no work other than that done on the piston, find the direction and magnitude of the work and heat transfer.arrow_forwardassuming that mass = 2150 kg K = 80.98 N/mm C =21.19 N/mm.arrow_forward1.
