Consider an AC voltage source which is supplying electric power to a network of parallel connected loads. These loads include a 13.25 kW electric heating load (purely resistive), an induction motor operating at rated conditions (7.5kVA at 0.85 power factor lagging), and a synchronous condenser operating at rated conditions (13 HP at 0.9 power factor leading).
(a) Draw the system described.
(b) What is the real power delivered by the source?
(c) What is the reactive power delivered by the source?
(d) What is the apparent power delivered by the source? (e) Sketch the power triangle for the source.

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.
