For the Figure, the cover gate AB closes a circular opening 143 cm in diameter. The minimum mass equal to . ton. Let h= 189 cm. Mass=? A 50 cm Water 6 m

Find the pressure magnitude in the Gasoline Pipe at the right side of the figure. Specific weight of water is 9.81 kN/m3 and specific weight of air is negligible. Oil SG= 0.79 Pgage = 376 kPa Gasoline SG = 0.70 Air 45 cm 50 cm Pipe 22 cm † 10 cm Water `Mercury SG= 13.6

X=10  ı need help, thanks

The figure belows shows a closed tank holding air and oil to which is connected a U-tube mercury manometer and a pressure gage, with L₁ = 3 ft, L₂ = 0.5 ft, and L3= 1.25 ft. The densities of the oil and mercury are 55 and 845, respectively, each in lb/ft³. Let g = 32.2 ft/s². Pgage = i Pressure gage lbf/in.2 Air Determine the reading of the pressure gage, in lbf/in.2 (gage). Oil (p=55 lb/ft³) Pam Mercury (p=845 lb/ft³) g=32.2 ft/s²
