Arefrigerator uses refrigerant-134a as the working fluid and operates on the ideal vapor-compression refrigera- tion cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 30 percent and leaves the compressor at 60c. if the compressor consumes 450 w of power, determine a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

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

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
