1) A venturi meter is a device in which pressure energy is converted into kinetic energy to measure the rate of flow of liquid through pipes. It was invented by American engineer Clemans Herchel and named by the Italian physicis Govanni Venturni. It works on the basic principle of Bernoulli's equation. Oil (Sai= 0.86) flows through a 30-cm diameter pipe and through the contraction shown below. The diameter of the contracted section is 15 cm. (a) Compute the volumetric flowrate of the oil. (b) If instead of oil, the pipe carries water at 50° C, what is the pressure in the venturi when incipient cavitation occurs?

Question
Transcribed Image Text:1) A venturi meter is a device in which pressure energy is converted into kinetic energy to measure the rate of flow
of liquid through pipes. It was invented by American engineer Clemans Herchel and named by the Italian physicist
Giovanni Venturi. It works on the basic principle of Bernoulli's equation. Oil (S = 0.86) flows through a 30-cm
diameter pipe and through the contraction shown below. The diameter of the contracted section is 15 cm. (a)
Compute the volumetric flowrate of the oil. (b) If instead of oil, the pipe carries water at 50° C, what is the pressure
in the venturi when incipient cavitation occurs?
