Question
11.3.2 Determining the Resultant Force e i The resultant force corresponds to the hydrostatic pressure at the planar centre of force C of the active surface. Thus, the height of water level s must again be differentiated: Meaning: Aact Superficial content of active surface b-75 mm- Width of liquid vessel Pe- Hydrostatic Pressure at planar centre of force Fp- Resultant force for hydrostat. Pressure on active surface: cal len 209 For s 100 mm: (trapezoidal profile) 11.6 = . g. (s-50mm) And Aact-100mm. b The resultant force is produced as 43 Aact -2. Aact 11.7 rp = r.. Aact 11.1 Last Modified: Fall Semester 2015- 2016Explanation / Answer
The value and unit of density will depend on the unit of other quantities in the formula.
Normally, it is better to plug all the values in SI unit system.
Therefore, if you are plugging the value of Pressure in N/m^2, value of g in m/sec^2, then it is better to plug the value of density in kg/m^3. If the liquid being used is water, then its density is 1000 kg/m^3. If it is any other liquid, then the density must be given. Also, you will have to change the value of s to meters. mm can be converted to meters by dividing it by 1000.
