Problem $1$: Energy Equation

Copy the figure below. Assuming steady flow of an ideal incompressible fluid, find the pressure

at point $A[].$ The pipe diameter is $12\mathrm{.}0$ in at point A and $6\mathrm{.}0$ in at point B $.$ At point B $,$ the

pressure head is $2\mathrm{.}0$ ft and the velocity is $8\mathrm{.}0f\frac{t}{s}.$ Use $g=32\mathrm{.}0f\frac{t}{s^2}$ and $=52\mathrm{.}0l\frac{b}{f}{t}^3.$
