Example. The pressures at sections $1$ and $2$ are $56\mathrm{.}3$ psi and $58\mathrm{.}2$ psi, respectively. Determine the mass rate $(l\frac{b}{s})$ of the gasoline in the pipe. $($Specific weight for gasoline Assume $z_1=z_2)$

Mass rate $(l\frac{b}{s})=$ specific weight $(l\frac{b}{f}{t}^3)**Q(f\frac{t^3}{s})$

Note: Do not assume the density is negligible or cancels out on Bernoulli Equation
