Water fl owing in a smooth 6-cm-diameter pipe enters a
venturi contraction with a throat diameter of 4 cm.
Upstream pressure is 120 kPa. If the pressure in the throat
is 50 kPa, what is the fl ow rate, assuming ideal frictionless
fl ow?
( a ) 7.5 gal/min, ( b ) 236 gal/min, ( c ) 263 gal/min,
( d ) 745 gal/min, ( e ) 1053 gal/min
