PMV is a calculated index to represent the thermal comfort of representative occupants using the ASHRAE thermal sensation scale from -3 to +3, corresponding to the seven categories "cold," "cool," "slightly cool,"
"neutral," "slightly warm," "warm," and "hot." The PPD index assumes that people voting +2, +3, -2, or -3 on
the PMV index are
O A. Satisfied
O B. Uncooperative
O C. Dissatisfied
O D. Misunderstood

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Assuming compressible flow of air and that the measurements are done at flagstaff a pitot static tube that gives the difference of total and static pressure measures 0.35 m of mercury. what is the velocity of air? assume the temperature to be 300k. (submit your excel or matlab calculation sheet)
