How is the purging of a carbon filter achieved?
A) Gasoline vapor held within the filter is continuously being drawn in by the engine.
B) The engine draws in fresh outside air through the carbon filter.
C) No purging takes place; the filter needs to be replaced at regular service intervals.
D) The gasoline vapor stored in the filter is transferred to the intake manifold by the fuel pump.

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.
