Cc = (1.75*1.75)/(2*2),
Cc = 0.766.
Cc = 0.766.

0. 87 is the right answer.
Because the Co-efficient of contraction is= the area of vena-contracta/area of the orifice.
Because the Co-efficient of contraction is= the area of vena-contracta/area of the orifice.

Cc= 0.875*0.875(r1*r1)/1*1.
= 0.765.
= 0.765.

0.766 is the right answer as it is written ratio of area. So if 1.75pow2 ÷2 pow 2 gives 0.766.

Area of the jet at vena-contracta/ area of orifice = Cc.
