A hydraulic press has a ram of 30 cm diameter and a plunger of 4.5 cm diameter. What is the weight lifted by the hydraulic press when the force applied at the plunger is 600 N?
An open tank contains water upto a depth of 2m and above it an oil of specific gravity 0.9 for a depth of 1m. The pressure intensity at the bottom of tank is [Take g  9.81 m/s^{2}]
Pascal’s law states that pressure at a point is equal in all directions
∴ Gauge pressure = Absolute minus atmospheric pressure
For a real fluid moving with uniform velocity, the pressure
(d) In case of a real fluid moving with uniform velocity, the velocity head and pressure head are dependent on each other and their total sum remains constant. The pressure is thus independent of both depth and orientation, but in case of fluids under static condition, the pressure would depend on depth.
If a Mohr circle is drawn for a fluid element inside a fluid body at rest, it would be
