Which of the following loss is not considered while calculating the total head loss between the inlet well and D/s FSL?

Which of the following loss is not considered while calculating the total head loss between the inlet well and D/s FSL? Correct Answer Loss due to contraction of section

The head loss between the inlet well and the D/s FSL is given by adding the losses due to entry, exit, loss due to sudden enlargement and loss due to friction in the pipe. HL = 0.5 V22/2g (Entry loss) + (V2 – V3)2/2g (sudden enlargement loss) + fLV32/2gd (Friction loss) + V32/2g (Exit loss) Where, V2 = Velocity of entry in pipe, V3 = Velocity through the pipe, L = assumed pipe length, d = diameter of the pipe, f = Darcy’s coefficient of friction = 0.012 and g = acceleration due to gravity.

Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Two person X and Y together can make 25% of total number of bricks in 4.8 days. Another person Z can make 50 bricks in a day. What is the time taken by person X and Z together to make the total number of bricks? I. Dimensions of a brick is (3cm × 4cm × 5cm) while the dimension of a cuboids when all the bricks are put together is (72cm × 80cm × 50cm) and ratio of number of days taken by X and Y alone to make the total number of bricks is 3 : 2. II. The total number of bricks is 4800 and person Y can make 150 bricks in day. III. Total volume of all the bricks together is 1.008m3 and dimension of a bricks is (5cm × 6cm × 7cm) and time taken by Z to make total number of bricks is 200 % more than the total time taken by person Y to make total number of bricks.
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.

An inlet tap can fill water at the rate of 20 litres per minute. Now, before opening the inlet tap they found a leak in the tank which can empty the tank in 8 hours. They could not repair the leak and opened the inlet tap when the tank was full and it empties the tank in 10 hours. Find the capacity of tank.
An inlet tap can fill water at the rate of 12 liters per minute. Now, before opening the inlet tap they found a leak in the tank which can empty the tank in 6 hours.
