A pump is used in a building to lift water from a ground floor. The pump is pushing 60l/sec of water through a 0.1m diameter to above floor which is 5m high If the average velocity in the pipe is 6m/s. what will major energy loss if the dynamic viscosity of water is 8.9 x 10-4s. Due to vibration and noise issue in a pipe the velocity of pump is decided to set at 2.5 m/s. What will new major energy? Calculate the minor energy loss if length of the pipe is 15m. use f = 0.03, = 1, = 0.9 Analyse the relationship between frictional energy loss under different gravitational flow conditions
9. If the blood viscosity is 2.7x10-3 Pa.s, length of the blood vessel is 1 m, radius of the blood vessel is 1 mm, calculate the tubular resistance of the blood vessel (in GPa.S/m3 ).

Duct Pressure Drop: Determine the pressure drop, in inches of H20, for 300 feet of 12" diameter duct with 600 CFM of air flow. If the size is reduced to 10", what is the pressure drop? If the duct is instead changed to a rectangular duct 10"x14", what is the pressure drop?. Duct sizing: When reviewing the mechanical plans for an office building, you notice that the ME has run an 18" diameter duct above a ceiling where you know there is a beam obstruction. You determine that there is a maximum of 12" of space between the top of the ceiling and the bottom of the beam. If this duct carries 2,000 CFM, determine the equivalent rectangular size of ducting that you would propose the engineer, so that the pressure drop remains similar. What is the resultant velocity (FPM) in both the round duct and the rectangular duct?

A 1.5-inch diameter pipe extends vertically from the bottom of the tank and is 5 m long. The oil level in the tank remains constant at 3 m above the bottom of the tank. In a case with friction the discharge speed can be obtained in the form of the following Equation. Calculate the flow rate of oil discharged per hour. Assume that the pipe is commercial steel (ε=0.05 mm). V= 2gh +f-
