ONLINE CALCULATIONS OF HYDROSTATICS

1. The force of hydrostatic pressure on a flat rectangular surface

   \( P(H,B,\rho ,h_{1},p_{m},p_{vac})=B \cdot\left ( 9.81\left ( H\cdot h_{1}-\frac{H^{2}}{2} +H^{2}\right )\cdot\rho -H\cdot p_{vac}+H\cdot p_{m} \right ) \)

2. Coordinate of the center of hydrostatic pressure on a flat rectangular surface

   \( h_{D}(H,B,\rho ,h_{1},p_{m},p_{vac})=\frac{\left ( 981\cdot H \cdot h_{1} + 327 \cdot H ^{2}\right ) \cdot \rho - 100 \cdot H \cdot p_{vac} + 100 \cdot H \cdot p_{m}}{\left ( 1962 \cdot h_{1} + 981 \cdot H \right ) \cdot \rho -200 \cdot p_{vac} + 200 \cdot p_{m}} \)

Decimal digits in numbers are separated by a dot. For example 4.5 (4,5)

What is the pressure "\(p_{0} \)" on the free surface of the liquid? ""
