It is an instrument used to measure the discharge of liquid flowing in a pipe. It consists of three parts i.e. the converging cone, the throat and the diverging cone. The length of the divergent cone is made about three to four times longer than that of the divergent cone in order to avoid tendency of breaking away the stream of liquid and to minimize frictional losses. It may be noted that
a) The velocity if liquid at the throat is higher than that of inlet.
b) The pressure of liquid at the throat is lower than that of inlet.
c) The velocity and pressure of liquid flowing through the divergent portion decreases.
The discharge through a Venturimeter is given by:
a) The velocity if liquid at the throat is higher than that of inlet.
b) The pressure of liquid at the throat is lower than that of inlet.
c) The velocity and pressure of liquid flowing through the divergent portion decreases.
