Question
Example: Pressure in A Decelerating Tank of Liquid
The tank on a trailer truck is filled completely with
gasoline, which has a specific weight of 42 lbf/ft³
(6.60 kN/m³). The truck is decelerating at a rate of
10 ft/s² (3.05 m/s²).
(a) If the tank on the trailer is 20 ft (6.1 m) long and if the pressure at the top
rear end of the tank is atmospheric, what is the pressure at the top front?
(b) If the tank is 6 ft (1.83 m) high, what is the maximum pressure in the tank?
Now if the tank is assumed to be opened
find the following:
If the tank on the trailer is 20 ft (6.1 m) long and 6
ft (1.83 m) high, what is the pressure at the top
front and bottom rear? and what is the maximum
pressure in the tank? The width of truck is 2 m.
