A closed cylindrical tank $2\mathrm{.}4m$ in diameter and $7\mathrm{.}5m$ long is completely filled

with gasoline, of specific gravity $0\mathrm{.}90.$ The tank, with its long axis horizontal is

pulled by a truck along a horizontal surface. Draw the whole diagram and label

its parts $($long axis, horizontal surface, rear wall, front wall, etc$).$

a$.$ Determine the pressure difference between ends along the long axis of the

tank when the truck undergoes an acceleration of $1\mathrm{.}5\frac{m}{s^{{?}^{{?}^{?}}}}2.($Ans$.10\mathrm{.}125$kpa $)$

b$.$ Determine the force on the rear wall $($Ans$.93\mathrm{.}7kN)$

c$.$ Determine the force on the front wall $($Ans$.47\mathrm{.}9kN)$
