    Question

    Which of the following Instrument is used to measure

    rate of fluid, works on Bernoulli’s theorem?
    A Viscometer Correct Answer Incorrect Answer
    B Voltmeter Correct Answer Incorrect Answer
    C Venturimeter Correct Answer Incorrect Answer
    D Ohmmeter Correct Answer Incorrect Answer

    Solution

    A venturimeter is a device used for measuring the rate of flow of a fluid flowing through a pipe.The working of venturimeter is based on the principle of Bernoulli’s theorem. It states that in a steady, ideal flow of an incompressible fluid, the total energy at any point of the fluid is constant. The total energy consists of pressure energy, kenetic energy and potential energy or datum energy.
