Question 13 A horizontal venturi meter is used to measure the flow rate of oil of specific gravity 0.9. The inlet
and throat diameter of a horizontal venturi meter are 400 mm and 150 mm respectively. The
pressure intensity at inlet is 0.20 N/mm' while the pressure head at the throat is 360 mm of
mercury. Take the coefficient of discharge of venturi meter 0.98.
a) Calculate difference in Pressure head.
b) Calculate theoretical discharge.
c) Calculate actual discharge
