What force is applied on a piston of area of cross section 2 cm2 to obtain a force 150 N on the piston of area of cross section 12 cm2 in a hydraulic machine?
66640 Pa pressure is exerted by 0.50 m vertical column of a liquid. If g = 9.8 Nkg−1, calculate the density of the liquid.
At a given place, a barometer records 70 cm of Hg. If the mercury in the barometer is replaced by water, what would be resulting in reading? (Density of Hg = 13600 kg/m3; Density of water = 1000 kg/m3)
The atmospheric pressure at a place is 650 mm of Hg. Calculate this pressure in Pascals (Pa).
Name three applications of Pascal's law.
State Pascal's law.
Hydraulic lift works under the principle of _______.
State Pascal’s law.
Consider a water tank shown in the figure. It has one wall at x = L and can be taken to be very wide in the z direction. When filled with a liquid of surface tension S and density ρ, the liquid surface makes angle θ(θ << 1) with the x-axis at x = L. If y(x) is the height of the surface then the equation for y(x) is:
(take θ(x) = sin θ(x) = tan θ(x) = `dy/dx`, g is the acceleration due to gravity)
