4. In a vertical pipe carrying water, pressure gauges are inserted at points A and B where the pipe diameters are 0.2 and 0.08 m respectively. The point B is 3 m below A, and when the flow rate down the pipe is 0.02 m/s, the pressure at B is 15 kPa greater than at A. Assume that the losses in the pipe between A and B can be expressed as: da -02m de - 0.08 m k- 2g where v is the velocity at A. a) Find the value of k. b) If the gauges at A and B are replaced with tubes filled with water and connected to a u- tube containing mercury of relative density 13.6, what is Rp?

Figure 5 shows a pump connected to a large tank of water. Water flows out of the tank through the pump into a galvanized iron pipe of diameter D = 80 mm at a length, L = 40 m. At the end of the pipe, water exits through a nozzle of diameter D2 = 50 mm. With the height of water h, the pump adds 30 kW of power to the water resulting in a volumetric flowrate of Q=0.05 m³/s. Ignore the length of the nozzle and assume that the velocities are uniform. By using the same height of water and pipe, explain and justify with your calculation, which parameter(s) will be affected if the pump is to be removed from the system. ♡ (1) D2 = 50 mm h (2) Ритp L= 40 m D= 80 mm Figure 5
Water flows initially from tank A to B through a single pipeline which is 150 mm in diameter and 150 m in length, shown in the figure below. Further development requires that the flow rate is to be increased by 30 % by installing a second pipe in parallel, indicated by the dotted line and 82 m in length, running from A to c. The coefficient of friction for each pipe is 0,015. Determine the diameter of this new pipe. = ? L= 82 m 4 m 0 = 150 mm L= 80 m = 150 mm L = 70 m
Oil of specific gravity 0.8 flows through a pipe of 0.25 m diameter. An orifice of 0.1 m diameter is fitted to the pipe to measure the flow rate. A mercury manometer fitted across the orifice records a reading of 0.8 m. Calculate the coefficient of discharge of the orifice meter if the flow rate measured by it is 0.082 m3/s.

QUESTION 2 A venturi meter with a throat diameter of 100 mm is fitted in the inclined pipeline of 200 mm diameter with oil of specific gravity 0.88 flowing upwards. The venturi meter coefficient is 0.96. Two pressure gauges are fitted at tapping points, one at the throat reads the vacuum pressure of 40 cm of mercury and the other in the inlet pipe 320 mm below the throat is 20.231 N/cm2. If the loss of head in the main and throat is 0.35 times the kinetic head of the pipe, determine: 2.1 the volume flow rate of oil through the pipe 2.2 the difference in level in the two limbs of the mercury manometer if it is connected to the tapping points and connecting pipes are filled with the same oil

A farmer must pump at least 100 gallons of water per minute from a dam to a field, located 25 f t above the dam and 2000 f t away. She has a 10 hp pump, which is approximately 80% efficient. Find the minimum size of smooth plastic piping she needs to buy, given that the piping is sized by the half-inch. Use ν = 10−5f t/ s. Ignore minor losses.2

A vertical pipe is shown in figure 1 below. The pipe tapers from 50 mm in diameter to 25 mm in diameter. If 2 liters of water per minute flow upwards through the pipe the pressure difference across the pipe is 35 kpa. Calculate the flow downwards through the pipe if the pressure across the pipe is to be zero. The losses across the pipe are given by h1=k((v2) ²-(v1)²)/2g,where v1 and v2 are the velocities in the 50 mm and the 25 mm sections respectively.
