A non viscous inconpressible liquid is flowing from a horizontal pipe of non-uniform cross section as shown, Choose the correct option

Options

A. speed of liquid at section-2 is more
B. volume of liquid flowing per second from section-2 is more
C. mass of liquid flowing per second at both the sections is same
D. pressure at section-2 is less

Answer

A, C, D

Explanation

From continuity equation Av- constant
`v_(2)gtv_(1)` as `A_(2)ltA_(1)`
From Bernoulli's equation,
`p+1/2rho v^(2)=` constant (as `h=`constant)
`p_(2) ltp_(1)` as `v_(2) gtv_(2)`.
