10. A well-fitting piston with 4 small holes in a sealed water-filled cylinder, shown in the figure, is pushed to the right at a constant speed of 4 mm/s while the pressure in the right compartment remains constant at 50 kPa gage. Disregarding the frictional effects, determine the force F that needs to be applied to the piston to maintain this motion. Ans: 0.565 kN d₁-3 cm Water Piston d₂= 12 cm Hole d = 2 mm P-50 kPa Cylinder
