Agear with a diametral pitch of 3 inch-1 has 35 teeth and meshes with a 70- tooth gear. the larger gear rotates at 300 rpm cw. determine: i. the pitch circle diameters ii. the circular pitch iii. the rotational speed of the smaller gear

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
