Calculate the velocity over the notch (V1) and the velocity through the pipe (V3) if the full supply discharge is 2 cumecs. The area of flow over the trapezoidal notch is 0.58 m2. Assume the value of diameter of the pipe used as 1 m.

Calculate the velocity over the notch (V1) and the velocity through the pipe (V3) if the full supply discharge is 2 cumecs. The area of flow over the trapezoidal notch is 0.58 m2. Assume the value of diameter of the pipe used as 1 m. Correct Answer V1 = 3.44 m/sec and V3 = 2.54 m/sec

The velocity over the notch (V1) = full supply discharge / Area over the notch and the velocity through the pipe (V3) = Full supply discharge / Area of pipe. V1 = 2/0.58 = 3.44 m/sec V3 = 2/0.785 = 2.54 m/sec (Area of pipe = 0.785 m2).

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

Two pipes are connected to tank 1 and one pipe connects tank 1 and tank 2 at the bottom of both tanks. At first pipe A and pipe B will filling tank 1 and then pipe C would be opened to fill tank 2. Capacity of tank 1 is twice capacity of tank 2. Pipe C takes 8 minutes to fill the whole tank 2 wherein discharging capacity of pipe C is 62.5 liters per minute. Ratio of time taken by pipe A and B to fill the tank when operating alone is 4 : 5 then find approximate discharging capacity of pipe A and B in liters/ minute if both the pipes discharge equal amount of water in tank. Time taken by pipe A and B to fill the tank 1 is 20/ 3 minutes
A container of 425 liters was filled with chemicals through two pipes. The first pipe was kept open for 5 hours more than the second pipe. If the first pipe remains open for as long as the second pipe remains open, and the second pipe remains open for as long as the first pipe remains open, then the quantity of chemical filled by the first pipe was half the quantity of chemical filled by the second pipe. If both the pipes are opened simultaneously, the tank will be filled in 17 hours. For how long was the second pipe open?
