Q1: In a venturemeter used for measuring the flow ofoil (-0.85) through a horizontal pipeline, the pipe diameter is 2.4 times the diameter at the throat. Connections are made from the entrance to the meter and the throat to a vertical L tube containing mercury If the difference level between the fluids in the U - tube arms is (x +) in em, where S.N. is student serial number. Neglect friction in the pipe. Find an expression in terms of x for the velocity of the oil in the pipe.
Q1/ Neglecting losses, determine the discharge in Fig. below Oil sp gr 0.75 3 ft 4 ft 4 in, diam Water
What is the volume flow rate for water (viscosity= .0010 Pa×s) through a length of pipe L= 0.60m and pipe radius r= 1.03cm if the pressure difference across this length of pipe is 5.2 kPa? Note that 1 kPa= 1000 Pa. What would the volume flow rate be if the same pipe had a radius that is reduced by 21% (i.e. the radius is 79% of its previous value)? Let's call this flow rate Q1. What is the ratio of Q1 to the original flow rate Q? Express this as a decimal number.
Answer the question considering the information given in the picture a) Calculate the flow rate Q.
The flow carried by pipe below discharges into the open atmosphere. If the pipe length is 300 m, diameter is 150 mm and roughness of 0.0025 mm, write the equation(s) required to determine the maximum discharge.
A liquid (SG = 0.562) is being pumped from a reservoir as shown. The pressures at points 1 and 2 are -9 psi and 41 psi, respectively. The rate of flow in the pipe is 0.898 ft3/s. What will be the rating of the pump (in horsepower) if its efficiency is 90%? Neglect energy (friction) losses in the system. Use x = 5 ft., y = 9 ft. Use 1 hp = 550 lb-ft/s. Round off to two decimal places.
An instrument popular in the beverage industry is the targetflowmeter in Fig. A small flat disk is mountedin the center of the pipe, supported by a strong but thin rod.(a) Explain how the flowmeter works. (b) If the bendingmoment M of the rod is measured at the wall, derive a formulafor the estimated velocity of the flow. (c) List a fewadvantages and disadvantages of such an instrument.
An orifice having an area of 0.0003 m² is located on the vertical side of a tank. The tank has a constant cross sectional area of 0.40 m². It takes 312 seconds to lower the head from 1.20 m to 0.60 m. Using c=0.60, which of the following most nearly gives the head in meter after 240 seconds from an initial head of 1.20m?
