A Venturimeter having a diameter of 75 mm at the throat and 150 mm diameter at the enlarged end is installed in a horizontal pipeline 150 mm diameter carrying an oil of specific gravity 0.9. The difference in pressure head between the enlarged end and the throat recorded by a U-tube manometer is 175 mm of mercury. Determine the discharge through the pipe. Assume the coefficient of discharge of the meter is 0.97.

Water is siphoned from the tank shown in the figure below. The water barometer indicates a reading of 30.2 ft. Determine the maximum value of h allowed without cavitation occurring. Note that the pressure of the vapor in the closed end of the barometer equals the vapor pressure. Assume h1 = 6.5 ft, d2 = 2.8 in., d2 = 5.4 in.

Kindly show complete or detaled solution.  A rectangular water tank is divided by a partition into two chambers, as shown. In the bottom of the partition is a round, sharp-edge orifice with a diameter of 150 mm. The coefficient of discharge is equals to 0.62. At a certain instant, the water level in B is 2.5 m higher than A. How long will it take for the water surfaces in the two chambers to be at the same level? a. 399 s b. 157 s c. 279 s d. 220 s

2. A nozzle 3 m long has a diameter of 1.3 m at the upstream end and reduces linearly to 0.45 m diameter at the exit. A constant flow rate of 0.12 m /sec is maintained through the nozzle. Find the acceleration at the midpoint of the nozzle. Hint: velocity at any point is equal to the flow rate divided by the area of the pipe at that point. [Ans. a=0.02579 m/s/s] 3. Water accelerates in an upward sloping pipe at a rate of 1.5 m/s?. The pipe slope is set at 40 degrees and has a length of 6 m. If the pressure is 63 kPa at section 1, what will be the pressure at section 2? [Ans. P2=16165.52 Pa] 1

Question 3: 150 m long commercial steel pipe is to convey 30 L/s of oil (s=0.9, μ-0.038 N.s/m² from one tank to another (submerged discharge) where the difference in elevation of the free liquid surface is 2 m. The pipe entrance is flush and there is a fully open gate valve in the line. Using only basic scientific calculator, find the diameter theoretically required. Use k=0.19 for fully open pipe or follow the following table (Table 8.3).

What advantages does the automated method have over the manual method?

An oil of viscosity 8 poise flows between two parallel fixed plates which are kept at 60 mm distance. The pressure drop over the length of 150 cm is observed to be 4.5 kPa. The width of the plates is 0.2 m. The discharge of flow (in Ips) is [Assume laminar flow.]
