ONLINE CALCULATIONS OF HYDROSTATICS

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

   \( P(H,B,\rho ,h_{1},p_{m},p_{vac},h)=- \left ( \frac{\left ( \left ( \left ( 981Bh^{2}-1962BHh \right )h_{1}-654Bh^{3}+1962BHh^{2}-1962BH^{2}h \right )\rho +\left ( 200BHh-100Bh^{2} \right )p_{vac}+\left ( 100Bh^{2}-200BHh \right )p_{m} \right )}{\left ( 200H \right )} \right ) \)

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

   \( h_{D}(H,B,\rho ,h_{1},p_{m},p_{vac},h)={{\left(\left(3924\,h^2-5886\,H\,h\right)\,h_{1}-2943\,h^3+7848\,H \,h^2-5886\,H^2\,h\right)\,{\it ro}+\left(600\,H\,h-400\,h^2\right) \,{\it pvac}+\left(400\,h^2-600\,H\,h\right)\,{\it pm}}\over{\left( \left(5886\,h-11772\,H\right)\,h_{1}-3924\,h^2+11772\,H\,h-11772\,H^ 2\right)\,{\it ro}+\left(1200\,H-600\,h\right)\,{\it pvac}+\left(600 \,h-1200\,H\right)\,{\it pm}}} \)
