Hydrostatic laboratory report

Hydrostatic force is the part of fluid mechanics, and it study the situations of fluids, which are put at rest in stable equilibrium.F = ghcAMoment is the blend of a physical quantity multiplied by the distance. M = F x DDepth of centre pressure is where the hydrostatic force acts.hp = hc +Depth to the centroid is a centroid of the liquid been analysed.; y = Second mass moment of inertia. Icxx =

This hydrostatic report is going to emphasise on the centre of pressure on a vertical plane, in order to locate the magnitude of force, and centre of pressure on the submerged area of a plane vertical surface. To calculate has been used the following formula:mg = FhgdFhyd = ghcAMaterial Apparatus; Quadrant; Weight hanger (10g each disc); Water; Syringe.

Methods First, the equipment was put on the desk and aligned in the horizontal axis. Moreover, the disks of weight were located in the quadrant in order to equilibrate it, whereas the quadrant marker had to reach 0mm.Furthermore, the weight hanger was positioned in the left side of the apparatus with 20g. Also, water was add in height to balance, in order to get the hp and so on.

Identification The quadrant has 200mm inner and 100mm radius, tank width of 75mm and the balance arm with 200mm.

ResultsThe table below represent the data collected in the lab (mass and height of the water in centimetre). Following that, it was possible to find the force exerted by the weight, the moment, the centre of pressure hp and so on. Mass (kg)Force (N)Depth (m)hc (m)Icxx (m)Area(m^2)hp

Discussion In this lab report, using the formula F = mg helped to find the force in the weight hanger. Furthermore, with the value of the height of water, it was achievable to find the value of hc (depth /2), and from the formula Icxx = was possible to calculate the moment of inertia in the centre of quadrant, where a is the length which the value was given (75mm) and b the height of the quadrant. After that, with the value of a and b was possible to know the result of centre of pressure hp = hc + .ConclusionTo conclude, the level of the water was growing due to the Fhyd acting in various stance, as well as the centre of pressure was depending on the height of the water. Nevertheless, the marks might be with error, because of the inexact measurement of human being.
