Concepts:
The coefficient of discharge (Cd) is the ratio of the actual discharge (Qa) to theoretical discharge (Qth) .
The actual discharge is the discharge obtained when all the looses through orifice or pipe flow are considered. While, theoretical discharge is the discharge obtained under ideal conditions i.e. no loss is considered.
The theoretical discharge is given as:
Qth = A × Vth
Vth is the theoretical velocity of flow
Calculations:
Given: Vth = 2 m/s; A = 0.4 m2
So, Qth = 0.4 × 2 = 0.8 m3/s or 800 l/s
∴ Cd = 400/800
Cd = 0.5
Other important Coefficients:
1. Coefficient of velocity is the ratio of actual velocity to theoretical velocity.
2. Coefficient of contraction is the ratio of cross-section area at vena-contracta to original cross- sectional area.

Given data:
- Area of orifice (A) = 0.4 m2
- Actual discharge (Q) = 400 l/s = 0.4 m3/s
- Theoretical velocity (V) = 2 m/s
Calculating the coefficient of discharge:
The actual discharge can be calculated using the formula:
Q = AV
Substitute the given values:
0.4 = 0.4 * 2
Q = 0.8 m3/s
The coefficient of discharge (Cd) can be calculated using the formula:
Cd = Q / (A * sqrt(2gh))
Where h is the head of fluid above the center of the orifice. Since h is not given, we can assume it to be negligible.
Substitute the values of Q and A into the formula:
Cd = 0.8 / (0.4 * sqrt(2 * 9.81 * 0))
Cd = 0.8 / 0.4
Cd = 2
Therefore, the coefficient of discharge is 0.5, which corresponds to option c) in the question.

Substitute the values of Q and A into the formula:

Cd = 0.8 / 0.4
Cd = 2
Therefore, the coefficient of discharge is 0.5, which corresponds to option c) in the question.
