Two standard gears in mesh have 48 and 102 teeth, respectively. Their diametral pitch is 10, and the pinion rotates at 60 rpm cw. Determine the center distance between the gears, the pitch diameters, the circular pitch, the pitch line velocity, the length of action, and the angular velocity of the gear.

What precautions should you take to prevent injuries when dealing with heavy loads?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

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
