Question : 193 of 200

Marks: +1, -0

A fluid flows through an orifice of an area 0.4

\m^2

with an actual discharge of 400 l/s. If the theoretical velocity of flow through the orifice is 2 m/s, what is the coefficient of discharge?

Solution:

V_{{\th }}=2 {\m} \/ {\s} ; {A}=0.4 {\m}^{2}

So,

\Q_{{\th }}=\A×\V_\th

=0.4 × 2=0.8 {\m}^{3} \/ {\s}

800 {\l} \/ {\s}

∴{\C}_{{\d}}=400 / 800=0.5
