Please solve this question!!
A 25 mm diameter venturimeter is installed in a 75 mm diameter pipe to
measure the flow rate of gas. The absolute pressure at the inlet and throat of
the venturimeter are 135 kN/m2 and 120 kN/m2
, respectively, and the density
at the inlet is 1. 6 kg/m3
. Determine velocity at the inlet and mass flow rate
of the gas. (y =1.41, R=287 J/kg K for air)
