Calculate the rate of flow of glycerine of density `1.25 xx 10^(3) kg//m^(3)` through the conical section of a pipe if the radii of its ends are 0.1m and 0.04 m and the pressure drop across its lengths is `10N//m^(2)`.

Options

A. `A_(1)A_(2) sqrt((20)/(rho(A_(1)^(2) -A_(2)^(2))))`
B. `A_(1)A_(2) sqrt((20 rho)/((A_(1)^(2) - A_(2)^(2))))`
C. `A_(1)A_(2)sqrt(40/(rho(A_(1)^(2)-A_(2)^(2))))`
D. None of these

Answer

A
