Water from a reservoir passes over a dam through a turbine and discharges from a 60-cm ID pipe at a point 40 m below the reservoir surface. The turbine delivers 1 MW. a. Draw the system and write the relevant form of the mechanical energy balance. b. Calculate the required flow rate of water in m3 /min if friction is neglected. (Note: The equation you will solve in this problem has multiple roots. Find a solution that is physically relevant.) c. If friction were included, would a higher or lower flow rate be required

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

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.
