Physics

$P_1 =322095.92\ Pa$

Explanation:

given,

height = z = 11 m

velocity at bottom = v₁ = 1 m/s

velocity at the top = v₂ = 12 m/s

pressure at the top = P₂ = 207000 Pa

Pressure at the bottom = P₁ = ?

using Bernoulli equation

$P_1 + \rho\dfrac{v_1^2}{2} = P_2 + \rho\dfrac{v_2^2}{2g} + \rho gz$

$P_1 = P_2 + \rho \dfrac{v_2^2-v_1^2}{2g} + \rho gz$

$P_1 =207000+1000\times \dfrac{12^2-1^2}{2\times 9.8} + 1000\times 9.8\times 11$

$P_1 =322095.92\ Pa$

Pressure at the bottom is equal to $P_1 =322095.92\ Pa$
