A waste water pipe has a length of 120 meters and is required to have a capacity of 50 L/s.The ground elevations are: 255.344 m @ upper end and 254.729 m @ lower end of the pipe.The minimum cover is 3.0 meters, and the permissible velocity range is 0.6 to 3.0 m/s.a) Identify the possible pipe sizes based on the Mannings nomograph in the Reference Moduleb) Draw a sectional view of one of the 2500 pipe. Show covers, pipe slope and inverts.c) Determine the partial velocity of the 2500 pipe using the hydraulics elements table in theReference Manual. Consider an actual discharge of 10 L/s.

- Diameter of the pipe (D) = 0.25 metersTo solve this problem accurately, let's follow these…

Water at 7 ft/s and 65 F flows in a 10 in schedule 40 pipe (inside diameter from Table A.III.1(SI) is 254.5 mm or 10.02 in from Table A.III.1(BU)). The pipe now bursts with an effective rupture area of twice the flow area of the pipe (ARupture = πD^2/2). Find the mass flow rate of water through the ruptured area. Assume that the flow velocity remains at 7 ft/s after the pipe ruptures. [Ans.: 239 lbm/s].
A Pipe carrying oil of specific gravity 0.92 changes in size from 250 mm at section 1 and 550 mm at section 2. Section 1 is 4.2 m below section 3 and the pressures are 90 kPa and 60 kPa respectively.

DIFFERENT QUESTION FOR REVISON-EXAMINATION Additional Questions: (1) A fluid of constant density flows at the rate of 15 Liters/ sec along a pipe AB of 100 mm diameter. This pipe branches at B into two pipes, BC and BD each of 25mm diameter and a third pipe BE of 50mm diameter. The flow rates are such that the flow through BC is three times the flow rate through BE and the velocity through BD is 4 m/s. Find the flow rates in the three branches BC, BD and BE and the velocities in pipes AB, BC and BE. Water is flowing through a pipe with a velocity of 7.2 m/s. Express this velocity as velocity head in meters of water. What is the corresponding pressure in kN/m2. (2) A pipe of 150mm bore is delivering water at a rate of 7500dm3/min at a pressure of 820 kN/m2.It connects by a gradually expanding pipe to a main of 300 mm bore which runs 3 m above it. The main is designed to withstand a maximum pressure of 814 kN/m2. Neglecting loses due to friction determine if the main will fail or…
