1. Water moves through a pipe with a cross-section area of 4.20 m^2 at speed of 2.25m/s with pressure P1 of 1.65x 10^5 Pa. If the cross section area at p2 is 1.80m^2 and the water has traveled up a distance of y=3.30 m, what is the pressure P2?

2. A 2.50 cm diameter piston pushes on an incompressible liquid with force F1. An object with a mass of 1.80x10^3kg sets on the second piston with a diameter of 3.20m. Find the force F1 to lift the mass?
