Q1:

The initial difference between liquid levels of two identical cylindrical vessels having their area of cross-section A, is H. Flow time T from one vessel to another through an orifice having coefficient of discharge Cd and area a will be

A

B

C

D

ANS:B -

T=2*A(√H1-√H2)/Cd*a*√2*g .
1st vassel empty comletly to fill the 2nd vassel then H2=0
then;
T=2*A√H1/Cd*a*√2*g.
