Aspeed-reducer gearbox containing a compound reverted gear train transmits 35 horsepower with an input speed of 1200 rev/min. spur gears with 20° pressure angle are used, with 16 teeth on each of the small gears and 48 teeth on each of the larger gears. a diametral pitch of 10 teeth/in is proposed. (a) determine the speeds of the intermediate and output shafts. (b) determine the pitch line velocities (in fumin) for each set of gears. (c) determine the magnitudes of the tangential, radial, and total forces transmitted between each set of gears. (d) determine the input torque. (e) determine the output torque, neglecting frictional losses.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
