Answer
$P_g = 278 kN/m^2 = 278 kPa$
Work Step by Step
$P_g = \dfrac{W}{A}$
$W = mg =(2000kg)(9.81m/s^2)$
$A = \dfrac{\pi D^2}{4} = \dfrac{\pi (0.3)^2}{4}$
$P_g = \dfrac{(2000kg)(9.81m/s^2)}{\dfrac{\pi (0.3)^2}{4}}\left(\dfrac{1kN}{1000\frac{kg\times m}{s^2}}\right) = 278 kN/m^2$
$P_g = 278 kN/m^2 = 278 kPa$
