Calculate full supply discharge for a free pipe outlet for the following data. Head on the upstream side above the centre line of pipe = 0.55 m Coefficient of discharge = 0.62 The diameter of the pipe = 25 cm

Calculate full supply discharge for a free pipe outlet for the following data. Head on the upstream side above the centre line of pipe = 0.55 m Coefficient of discharge = 0.62 The diameter of the pipe = 25 cm Correct Answer 9 lit/sec

The discharge can be computed by – Q = Cd. A. (2gH)1/2 where H is the head on U/s side measured from FSL of distributary up to the centre of pipe outlet and A is the area of cross-section of the pipe. Q = 0.62 x x (2 x 9.81 x 0.55)1/2 Q = 0.09 cumecs or 9 lit/sec.

A tank has an inlet pipe and an outlet pipe. If the outlet pipe is closed then the inlet pipe fills the empty tank in 8 hours. If the outlet pipe is open then the inlet pipe fills the empty tank in 10 hours. If only the outlet pipe is open then in how many hours the full tank becomes half-full?
A tank has an optional adjustable outlet pipe that can be attached to the tank at any height we want. This outlet pipe drains water from the tank at a constant rate, while the tank is being filled using another inlet pipe at a constant rate. If the outlet, pipe is attached at half the height of the tank, the tank, which is initially empty gets filled in 18 hours. If the outlet pipe is attached at height equal to two third height of the tank, the tank, which is initially empty, is filled in 16 hours. In how many hours will the tank, which is initially empty, be completely filled if the outlet pipe is not attached to the tank?
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: There are two inlet pipes A, B and two outlet pipes C, D inlet pipe B takes 7 hours more to fill the tank when compared to A. Two outlet pipes when working together can empty the tank in 3.5 hours and efficiency of both the pipe is same if all of them working together can fill the tank in 2 hours. Calculate the time taken by A to fill the tank. Quantity B: The ratio of efficiencies of two pipes A and B is in the ratio 3 ∶ 2 and that of pipe B and C is 1 ∶ 3. Pipe A and B are inlet pipes, pipe C is outlet pipe working together they can fill the tank in 7.5 hours. Calculate the time taken by A to fill the tank when working alone.
In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: Pipe A takes thrice the time taken by Pipe B to fill a tank. Together they can fill the tank in 15 hours, tank A and B is opened together for 4 hours and then Pipe A is closed and after 2 more hours Pipe B is closed and an outlet Pipe C is opened which when working alone can empty the tank in 10 hours. Calculate the time taken by C to empty the tank. Quantity B: A pipe A can fill the tank in 10 hours another pipe B can fill the tank in 15 hours and with the help of third pipe C they can fill the tank in 5 hours. Pipe A is opened for 4 hours then it is closed, pipe B is closed 3 hours before filling of tank and tank C is opened the whole time. Calculate the time taken to fill the tank

In a tank, 2 inlets and 1 outlet pipe are connected. Inlet pipe can fill the tank in 15 minutes and 20 minutes respectively while the outlet pipe can empty the tank in 5 minutes. If each pipe is opened after every 5 minutes starting with inlet pipe at 3: 00 pm which can fill the tank in 15 minutes and in the last outlet pipe is opened, then at what time tank will be emptied?
A tank has an inlet and outlet pipe. The inlet pipe fills the tank completely in 2 hours when the outlet pipe is plugged. The outlet pipe empties the tank completely in 6 hours when the inlet pipe is pluggeed. If there is a lekage also which is capable of draining out the liquid from the tank at half of the rate of outet pipe,them what is the time taken to fill the emty tank when both the pipes are opened?
Two outlets of a motor manufacturing company reported that revenue from outlet x in 2013 was down 11 percent from 2012. and revenue from outlet Y in 2013 were up 7 percent from 2012. If total revenue from outlet X & Y in 2013 was up 1 percent from 2012, what is the ratio of revenue from outlet X in 2012 revenue from outlet Y in 2012?
Two pipes A and B started to fill a cuboid-shaped swimming pool. They can individually fill the tank in 60 minutes and 72 minutes. The operator of the pipe didn’t notice that the outlet pipe C was also open. Due to the outlet pipe, the pool took 40 minutes to be filled. Find the time in which the outlet pipe can empty the pool?
