An orifice meter, with Cd = 0.61 is substituted by venturimeter with Cd = 0.98 in a pipe line carrying crude oil, having the same throat diameter as that of the orifice. For the same flow rate, the ratio of pressure drops for the venturimeter and orifice meter is -
1
(\(\frac{{0.98}}{{0.61}}\))2
2
(\(\frac{{0.61}}{{0.98}}\))2
3
(\(\frac{{0.98}}{{0.61}}\))
4
\(\frac{{0.61}}{{0.98}}\)
