A gas having a viscosity of 2.04 x10* kg/ms, the thermal conductivity of 0.0293 W/m °C, undergoes an isobaric non-flow heating process at a pressure of „P“ (= 95 x Reg. No.) kPa and temperature changes from 22 °C to „T“ (= 25 + Reg. No.) °C. The specific heat of the fluid is dependent on temperature and is given as C, = 1.44+82/(T+48); where T is in Celcius. During this process, its volume changes from 0.28 m³/kg to 0.658 m³/kg. %3D a. Sketch a schematic of the system along with the chosen system boundary and indicate the directions of various energy/mass flows. (5) b. Show the process on the Pv diagram. (3) c. Determine the amount of heat transfer during the process. (7) d. Estimate the work done during the process. (5) e. Calculate the changes in internal energy and enthalpy of the system. (5)

Q-3     Three blocks A, B, and C and a grooved block D have dimensions a, b, c, and d as follows: a = 40.500  0.025 mm               b =   52.000  0.075 mm c = 73.000  0.015 mm                d = 165.900  0.250 mm  Parts A, B, and C are standard parts supplied by vendors from the market, but  we are to machine part D according to the the width that you are asked to specify.                                                (a) Determine the mean gap w0 of w and its tolerance.                               (b) Determine the mean size of d (d0) that will assure that w ≥ 0.050 mm.
