The other tank is of capacity 2000 gallons and is 2 meters tall. One tank holds 1,000 gallons and is 3 meters tall. Imagine two tanks with bottom outlet valves positioned at ground level. Water gushes out at a much higher pressure when the tank is full compared to when it is almost empty. You will notice there is a stark difference between the two observations. Then take note once more when the tank is nearly depleted. connected to an overhead water tank without any pressure pumps)? If so, note the velocity and the amount of water gushing out of the taps when the tank is full. The water level is indicated on a scale on the side of the quadrant.Are the water lines in your home gravity fed (i.e. Water is added to the tank via a flexible tube and may be drained through a valve in the side of the tank. An indicator attached to the side of the tank shows when the balance arm is horizontal. Correct alignment is indicated on a circular spirit level mounted on the base of the tank. This assembly is mounted on top of an acrylic tank which may be levelled by adjusting screwed feet. The balance arm incorporates a hanger for the weights supplied and an adjustable counterbalance. This means that when the quadrant is immersed, the only force that gives rise to a moment about the knife edges is the hydrostatic force acting on the end face of the quadrant. The knife edges coincide with the centre of the arc of the quadrant. The Hydrostatic Pressure accessory has been designed to determine the static thrust exerted by a fluid on a submerged surface and enables comparison of the measured magnitude and position of this force with simple theory.Ī fabricated quadrant is mounted on a balance arm which pivots on knife edges.
