WebAug 31, 2024 · Solution First calculate the volume of mercury above point B. Use the density of mercury to obtain the mass, and from this, calculate force and pressure as in Example 1 from "Pressure." The preceding example shows that a mercury column 760.0 mm high and 1.000 cm 2 in area produces a pressure of 101.33 kPa (1 atm). WebThe formula used to calculate hydrostatic pressure is shown below: p=ρgh. Where, P is the pressure exerted by the liquid in Nm -2. ρ is the density of the liquid in kgm -3. g is the acceleration due to gravity considered as 9.81 ms -2. h …

WebF1 = P1 (π (d22 - d12) / 4) (1) where F1 = rod force (lb, N) d1 = rod diameter (in, mm) d2 = piston diameter (in, mm) P1 = pressure in the cylinder on the rod side (psi, N/mm2) 1 bar = 105 N/m2 = 0.1 Nm/mm2 The force produced on the opposite of rod side (2) - can be expressed as F2 = P2 (π d22 / 4) (2) where F2 = rod force (lb, N) WebTo calculate your pulse pressure, all you have to do is subtract the bottom number from the top number. Example: If your blood pressure was 120/80 mmHg, that would be 120 - 80 = 40. Why does my pulse pressure change when I take my blood pressure a few minutes apart? Pulse pressure variation is normal and expected.
