A tank containing gasoline is sealed and the gasoline is under pressure `P_(0)` as shown in the figure. The stored gasoline hs a density of `660 kg m^(-3)`. A sniper fires a rifle bullet into the gasoline tank, making a small hole `53 m` below the surface of gasoline. The total height of gasoline is `73 m` from the base. The jet of gasoline shooting out of the hole strikes the ground at a distance of `80 m` from the tank initially. If the pressure above the gasonline surface is `(1.39)alpha xx 10^(5)N//m^(2)` than `alpha` is- (The local atmospheric pressure is `10^(5)Nm^(-2)`)
