Reynold's no.=PVD/u(P=density).
Re directly proportional to u,
So if Re increases D will increase and vice versa.

Discharge coefficient (Cd) = Bord diameter (d) /Pipe Diameter (D).
Cd increase = d/D also in also increase.
Cd increase = d/D also in also increase.

Q = Cd.Ao(2gh)^1/2 /(1-(d/D)^4) ^1/2.
So, Cd =√1-(d/D)^4.
CD will decrease with increasing d/D.
So, Cd =√1-(d/D)^4.
CD will decrease with increasing d/D.

For a given Reynolds number, as the ratio of the orifice diameter to the pipe diameter (d/D) increases, the coefficient of discharge (Cd) will decrease.
The coefficient of discharge is the ratio of the actual flow to the ideal flow, and it's always less than one.
The value of Cd depends on several factors, including the Reynolds number, the shape of the nozzle, and the ratio of the pipe to Nozzle diameter.
