The force in (newton) required to lift a thin wire ring of diameter 2cm from a water surface of given surface tension at 21 C is 2N/cm

A 1m x 2m inclined plate is submerged as shown. The normal force acting on the upper surface of the plate due to the water (when taking atmospheric pressure into account) is most nearly (A) 68kN (B) 91kN (C) 203kN (D) 294kN Answer is 294kN please write the complete solution in Handwritten format with FBD

Consider the manometer tube shown in below Figure 1. It is filled with three differentincompressible fluids. The closed end of the tube is connected to a reservoir with aconstant pressure. For this configuration, calculate   i) the pressure in the reservoir in kPa, ii) the pressure in the reservoir as gage pressure in kPa, iii) the equivalent height of water, and iv) the equivalent height of mercury.

In the hydrostatic case shown in the following figure, a = 6 ft and c = 4 ft. Thespecific gravities of oil, mercury, and water are so = 0.8, sm = 13.6, and sw = 1.0. Pressurevariations in the air are negligible. What is the difference b in inches between the mercury levels?
