Apump steadily delivers water through a hose terminated by a nozzle. the exit of the nozzle has a diameter of 2.5 cm and is located 4 m above the pump inlet pipe, which ahs a diameter of 5.0 cm. the pressure is equal to 1 bar at both the inlet and the exit, and the temperature is constant at 20 degrees c. the magnitude of the power input required by the pump is 8.6 kw, and the acceleration of gravity is g= 9.81m/s2. determine the mass flow rate delievered by the pump in kg/s.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
