Small objects are delivered to the 2 - m inclined chute by a conveyor belt A which moves at a speed V1 = 0.3 m / s . If the conveyor belt B has a speed V2 = 0.9 m / s . and the objects are delivered to this belt with no slipping , the coefficient of friction Ik between the objects and the chute is 0.5 , calculate the incline angle ( Ⓡ ) of the chute .

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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.
