20. Determine the force F, with which it is necessary to push the piston of a horizontal cylinder base area S = 8 cm2 to a time t = 2,5 to extrude it through a circular orifice area S0 = 4 mm2 liquid layer thickness l = 5 cm. Density liquid ρ = 1g / cm3. The viscosity of the liquid is not taken into account.
