The air supply to an oil-engine is measured by being taken directly from the atmosphere into a large reservoir through a sharp-edged orifice 50 mm diameter. The pressure difference across the orifice is measured by an alcohol manometer set at a slope of arcsin 0.1 to the horizontal. Calculate the volume flow rate of air if the manometer reading is 271 mm, the relative density of alcohol is 0.80, the coefficient of discharge for the orifice is 0.602 and atmospheric pressure and temperature are respectively 755 mmHg and 15.8 °C. (You may assume \( R = 287 \, \text{J} \cdot \text{kg}^{-1} \cdot \text{K}^{-1} \))

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

If the difference of level indicated by the mercury in the U-tube is 50 mm, calculate the theoretical volume rate of flow through the meter.
Question 8 download image D The water in a large tank exits through a horizontal circular pipe of diameter D=0.01m and length L=94m. The centre of the exit of the pipe is h=1.0m below the water surface. We can assume that the flow entrance to the pipe is smooth so that there are no minor losses. The flow in the pipe is laminar, the friction factor can be assumed constant and can be found from h fD=64/Rep where the Reynolds number is based on the pipe diameter and mean flow speed in the pipe. Taking frictional losses into account, solve the resulting quadratic equation to calculate the speed of the flow out of the pipe. Give your answer in m/s to 2 decimal places. Use: kinematic viscosity given by v=0.00000114 m²/s density of water given by 1000 kg/m3 acceleration due to gravity of 9.81 m/s² A Moving to another question will save this response. >>
