Questions [12 -15] Oil treated as an incompressible (constant density) liquid is flowing steadily through an adiabatic and horizontal diffuser (opposite of a nozzle) and remains at a constant temperature (i.e., isothermal process). What happens to the following for the oil flow between the inlet and outlet? Velocity- Increases, Decreases ,Remains constant Internal Energy- Increases, Decreases, Remains constant Enthalpy -Increases, Decreases, Remains constant
A pump increases the water pressure from 100 kPa at the inlet to 900 kPa at the outlet. Water enters this pump at 15 degree C through a 1-cm-diameter opening and exits through a 1.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. Will these velocities change significantly if the inlet temperature is raised to 40 degree C?

Round your final answers to two decimal places. A pump increases the water pressure from 70 kPa at the inlet to 700 kPa at the outlet. Water enters this pump at 15°C through a 0.8-em-diameter opening and exits through a 3.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is0.58 kg/s Vinlet m/s m/s exit What is the velocity at the inlet if the...
A high-pressure pump has efficiency = 50%. The pump receives liquid water at 20 °C and 100 kPa and compresses the water to a pressure of 20 MPa. Assuming water to be an incompressible liquid, use a property table and a calculator, determine the temperature of the pump outlet (in °C).
(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...
A: Assuming that the pump is 50% efficient, what is the
highest elevation h that water from the fountain reaches assuming
that loss is otherwise neglible? Note that the water resevoir is at
the elevation as the nozzle.
B:If the nozzle is doubled, by what factor will h change if
the system is not otherwise changed?

A water pump delivers 6 hp of shaft power when operating. The pressure differential between the outlet and the inlet of the pump is measured to be 1.2 psi when the flow rate is 10 ft3/s, and the velocity changes to 5 ft/s from 2 ft/s as the water passes through the pump. Determine the mechanical efficiency of this pump assuming the water density to be 62.4 lbm/ft3 (written in decimal form with 3 significant figures).
