FLOW MEASUREMENT DEVICES. VENTURIMETER. VENTURIMETER. INTRODUCTION. In this meter the fluid is accelerated on expense of static pressure by its passage through a converging cone of angle 15-20 degree.
Bernoulli's Principle same as orifice meter
P↓ = V ↑
P = MIN
Why mercury is preferred as manometric fluid?
What is the quantity of liquid flowing through it when a differential manometer shows a steady deflection of 20 cm of mercury? (relative density of mercury is 13.6)
