When can a piezometer be not used for pressure measurement in pipes.

When can a piezometer be not used for pressure measurement in pipes. Correct Answer The fluid in the pipe is a gas

Explanation:

  • Piezometer is the simplest form of manometer used for measuring gauge pressure
  • One end of this manometer is connected to the point where the pressure is to be measured and the other end is open to the atmosphere
  • As one end is open to the atmosphere so it can’t be used for measuring the gas pressure
  • Gas pressure cannot be measured by means of piezometers because a gas forms no free atmosphere surface and it can’t be used when large pressures in the lighter liquid are to be measured

There are 12 pipes connected to a tank. Some of them are fill pipes and other are drain pipes. Each of the fill pipes can fill the tank in 8 hours and each of the drain pipes can drain completely in 6 hours. If all the pipes are kept open, an empty tank get filled in 24 hours. How many of the 12 pipes are filled pipes?
Five pipes P, Q, R, S, and T can fill a tank in 60 minutes, 20 minutes, 30 minutes, 8 minutes, 32 minutes respectively. Out of these five pipes, two have now been converted into emptying pipes such that their efficiency remains the same. When only one of the filling pipes and one of the emptying pipes operate, the tank can be filled in 60 minutes while another combination of emptying and filling pipe empties it in 8/45th of the time taken by the previous combination to fill the tank. Which pipes are converted into emptying pipes?
A set A of 6 pipes can fill the 60% of the tank in 6 minutes, another set B of 5 pipes can fill ¼ of the same tank in 4 minutes and a third set C of 4 pipes can empty ½ of the same tank in 8 minutes. If the efficiency of 2 pipes among the third set of pipes is increased to twice then find the per minute rate (in %) at which the tank will be full completely if all these 15 pipes are opened together?
A tank can be filled using pipes A, B, and C and can be emptied using pipe D. Pipes A & B can together fill the tank in 8 hours, pipes B & C can together fill the tank in 10 hours and pipes A & C can together fill the tank in 6 hours. If pipe D can alone empty the tank in 15 hours, in how much time will the tank be filled if all the pipes are simultaneously opened?
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.
Pipes A and C together can fill a tank in 26(2/3) hours and pipes B and C together can fill a tank in 48 hours. Pipes A and B are inlet pipes and pipe C is an outlet pipe. If all the three pipes are opened together, then in what time the tank will be filled?
A water tank has two types of inlet pipe viz. Type A and type B. 5 inlet pipes of type A and 25 pipe of type B are opened, the tank is filled in 30 minutes. Whereas it takes 1 hour if 3 pipes of type A and 12 pipes of type B are opened. In how many minutes does empty tank is filled by 8 pipes of type A and 12 pipes of type B.
In the following question, the 1st and the last part of the sentence/ passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R and S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct.  1. Blood pumps through the circulatory system of the human body. P. Over time, the increased pressure on the arteries can cause a wide range of problems. Q. Hypertension occurs when the force exerted against artery walls is abnormally high. R. Just as too much water pressure can damage pipes and faucets, high blood pressure can spell trouble. S. When blood is under pressure, it is like the water in the pipes of a house. 6. Small bulges, called aneurysms, may form in blood vessels
