1. Solve this problem in symbols first and then plug in numbers. pressurized vessel contains water with some air above it, as shown below. A multi-fluid manometer system is used o determine the pressure at the air-water interface, point F. Determine the gage pressure at point F in kPa gage. oil Air Mercury Data h, . 0.24 mi, h2 0.35 m and h3 . 0.52 m Assume the fluid densities are water 1000 kg/m2, oil: 790 kg/m2 and mercury(Hg): 13,600...

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...

(10 marks) An aerofoil is being tested in a wind tunnel using smoke to visualise the flow as shown in the figure below. The aerofoil is very long into the page so that the flow does not vary along the span and no fluctuation is seen over time. i. Is this flow one-, two-, or three-dimensional? ii. Is this flow steady or unsteady? iii. Is this flow uniform or non-uniform? iv. Do the smoke lines mark streamlines? Explain your answer...
