1a) What is pressure?
Pressure is defined as the force applied perpendicularly to a surface per unit area over which that force is distributed. It is a scalar quantity.

1b) Identify any practical applications of pressure in the plumbing industry.

  • Water distribution systems: Pressure is used to move water from a source (like a water tower or pump) through pipes to consumers.
  • Pressure testing: Pipes are subjected to high pressure to check for leaks or structural integrity before use.
  • Pressure relief valves: These devices use pressure principles to prevent over-pressurization in water heaters and other systems.

2a) Calculate the volume of water in litres.
Given:
Cross-sectional area (AA) = 2×1.5 m2=3 m22 \times 1.5 \text{ m}^2 = 3 \text{ m}^2
Tank height (HH) = 24 inches24 \text{ inches}
Tank is 23\frac{2}{3} full of water.

  1. Convert the tank height from inches to meters.

    H=24 in×0.0254 m1 in=0.6096 mH = 24 \text{ in} \times \frac{0.0254 \text{ m}}{1 \text{ in}} = 0.6096 \text{ m}

  2. Calculate the total volume of the tank.

    Vtank=A×H=3 m2×0.6096 m=1.8288 m3V_{tank} = A \times H = 3 \text{ m}^2 \times 0.6096 \text{ m} = 1.8288 \text{ m}^3

  3. Calculate the volume of water in the tank.

    Vwater=23×Vtank=23×1.8288 m3=1.2192 m3V_{water} = \frac{2}{3} \times V_{tank} = \frac{2}{3} \times 1.8288 \text{ m}^3 = 1.2192 \text{ m}^3

  4. Convert the volume of water from cubic meters to litres.

    Vwater_litres=1.2192 m3×1000 L1 m3=1219.2 LV_{water\_litres} = 1.2192 \text{ m}^3 \times \frac{1000 \text{ L}}{1 \text{ m}^3} = 1219.2 \text{ L}

    The volume of water in the tank is 1219.2 L\boxed{\text{1219.2 L}}.

    2b) Calculate the total pressure at the base of the tank.
    Assume standard atmospheric pressure (Patm=101325 PaP_{atm} = 101325 \text{ Pa}) and acceleration due to gravity (g=9.81 m/s2g = 9.81 \text{ m/s}^2). The density of water (ρ\rho) is 1000 kg/m31000 \text{ kg/m}^3.

  5. Calculate the height of the water column.

    hwater=23×H=23×0.6096 m=0.4064 mh_{water} = \frac{2}{3} \times H = \frac{2}{3} \times 0.6096 \text{ m} = 0.4064 \text{ m}

  6. Calculate the hydrostatic pressure (PhP_h) due to the water column.

    Ph=ρghwater=1000 kg/m3×9.81 m/s2×0.4064 m=3986.224 PaP_h = \rho g h_{water} = 1000 \text{ kg/m}^3 \times 9.81 \text{ m/s}^2 \times 0.4064 \text{ m} = 3986.224 \text{ Pa}

  7. Calculate the total pressure (PtotalP_{total}) at the base of the tank by adding atmospheric pressure to the hydrostatic pressure.

    Ptotal=Patm+Ph=101325 Pa+3986.224 Pa=105311.224 PaP_{total} = P_{atm} + P_h = 101325 \text{ Pa} + 3986.224 \text{ Pa} = 105311.224 \text{ Pa}

    The total pressure at the base of the tank is 105311.22 Pa\boxed{\text{105311.22 Pa}}.

    3a) Define air lock and why it's important in plumbing.
    An air lock occurs when a bubble of air becomes trapped in a pipe, preventing or significantly reducing the flow of liquid. It is important in plumbing because air locks can cause system malfunctions, leading to reduced water pressure, complete flow stoppage, or inefficient operation of pumps and heating systems, requiring removal to restore proper function.

    3b) If a plastic storage system of mixed vocational had a crack on it and leakage was seen; state 2 likely causes of such leakage in plastics.

    1. Material Degradation: Over time, exposure to UV radiation, harsh chemicals, or extreme temperatures can cause the plastic to become brittle and crack.
    2. Impact Damage: Physical force or impact, such as dropping the system or accidental striking, can lead to fractures or cracks in the plastic.
