The motor M of the hoist shown has the following parameters: mass of the crate=85 lb, acceleration at P= 3 ft/s2
. Determine the power supplied when the velocity at P is 3 ft/s and the
efficiency is 0.9.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
