The height of the down sprue is 175 mm and its CS are at the base is 200 mm². The CS area of the horizontal runner is also 200 mm². Assuming no losses, indicate the correct choice for-the time (second) required to fill a mould cavity of volume 10^6mm³. (Use g = 10 m/s²)

1. 2.67
2. 8.45
3. 26.7
4. 84.50

Correct Option: C

V_s = √2 × 10 × 175 × 10⁻³
= 1870 mm/s
Pouring time

t =	10⁶
	200 × 1870

t = 2.67 m/s
