A20 mm deep slot is being milled in a block of aluminum with k 850 n/mm2. the tool is 25 mm in diameter, and has 2 teeth. it is rotating at 14,728 rpm, and the chip load (feed per tooth) is 0.1 mm. how much power is consumed in kw?

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
