Engine oil at 40°C (ρ=875 kg/m³) flow into a 2.5 cm diameter horizontal pip with a velocity of 1 m/s and exits through a nozzle of 0.5 cm diameter. If the pressure drop is 538 kN/m², what must be the exit velocity?

H.W. (a) Derive an expression for the volumetric flow rate of a fluid flowing through an orificemeter. Write down the advantages and disadvantages of using orificemeter over a venturimeter. (b) Water is flowing through a pipeline of 50 cm ID at 30°C. An orifice is placed in the pipeline to measure the flow rate. Orifice diameter is 20 cm. If the manometer reads 30 cm of Hg, calculate the water flow rate and velocity of the fluid through the pipe. pwater at 30°C = 987 kg/m³. p = 13600 kg/m. Orifice co-efficient. = 0.6 3/5/2024 61 OPE

Consider the Lockheed SR-71 Blackbird shown in flying at a standard altitude of 25 km. The pressure measured by a Pitot tube on this airplane is 3.88 × 104 N/m2.Calculate the velocity of the airplane.

S CE - Oil is transported from A to B along a pipe of constant diameter. The pipe is inclined at 50° to the horizontal and B is at the higher elevation. Considering the flow from A to B, which statement is correct? O The pressure head is decreasing and the velocity head is increasing. O The pressure head is increasing and the velocity head is decreasing. O The pressure head and velocity head are both increasing. O The pressure head is decreasing and the velocity head is constant. O The pressure head and velocity head are both decreasing.
