Three piezometers located 1000 m apart bottom in the same horizontal aquifer. piezometer a is due south of piezometer b and piezometer c is to the east of the line ab. the surface elevations of a, b, and c are 95, 110, and 135 m, respectively. the depth to water in a is 5 m, in b is 30 m, and in c is 35 m. determine the direction of ground-water flow through the triangle abc and calculate the hydraulic gradient.

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.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
