A3 ft x 2 ft block moves down a 15 degree inclined slope at a speed of v = 0.2 ft/s over a thin layer (h = 0.0125 ft) of oil with a dynamic viscosity of 8.2 x 10^-2 lbf-s/ft^2. what is the weight of the block? draw fbd.

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
