Flow of water through an equal percentage valve is 900 liter

h^{ - 1}

at 30 % opening, and 1080 liter

h^{ - 1}

at 35 % opening. Assume that the pressure drop across the valve remains constant. The flow rate (in liter

through the valve at 45 % opening is ______(round off to nearest integer).

Options

none

Answer

1555.09

Solution

f = R^l^{-1}900⎯⎯ /rightarrow 30/\%

1080⎯⎯→35%

.

⇒1.2 = R.^{05}

.

0.1023=0.05ln R

lnR = 3.646

R = 38.32

.

.

f = 900 /times (38.32)^0.^{15}

f = /frac{1555.092L}{h}
