please assist all the questions please QUESTION 1 Municipal water is supplied to a Mega city through a large steel pipe of 2 meters diameter. A pipe of diameter 1m is attached to the large pipe to draw a certain quantity of water from the main line to supply water to another small city. Determine the mass flow rate of water in the large pipe before bifurcation if the mean flow velocity is 2 m/s. Determine the velocity of water in 1m diameter pipe if the velocity in large pipe after the bifurcation is measured to be 1.5m/s. Assume that the water flows smoothly in all sections of the pipe and there are no losses at the junction due to the pipe attached. [12M] QUESTION 2 Crude oil with sp.gr 0.92 enters with an inlet velocity of 2 m/s into a circular pipe of diameter 0.6m in an oil refinery. The diameter of the pipe gets reduced gradually to 0.5m along the flow direction. Determine the mean flow velocity of oil at the exit section of the pipe and the mass flow rate of oil. [11M] QUESTION 3 Water enters a circular pipe of diameter 150mm at the datum with a mean velocity of 2 m/s and 30N/cm² Determine the total energy per unit weight of water at a section which is 15m above the datum level.
