An open belt 100 mm wide connects two pulleys mounted on parallel shafts with their centres 2.4 m
apart. The diameter of the larger pulley is 450 mm and that of the smaller pulley 300 mm. The coeffi-
cient of friction between the belt and the pulley is 0.3 and the maximum stress in the belt is limited to
14 N/mm width. If the larger pulley rotates at 120 r. p.m., find the maximum power that can be trans-
mitted.

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.
