the Taylor's tool equation for machining a steel shaft with high speed cutting tool at a feed of 0.2mm/minute and a depth of cut of 2mm is given by VT^n=C. where C and n are constants. the following V and T observations were noted. V(m/min). 25. 35. T(min). 90. 20. calculate n and c

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
