(3) mg(d,-d2)(4) mgd,d26. There are two holes one each along the oppositesides of a wide rectangular tank. The cross-sectionof each hole is 0.01 m2 and the vertical distancebetween the holes is one metre. The tank is filledwith water. The net force on the tank in newtonwhen the water flows out of the holes is (densityof water 1000 kgm-3)(1) 100(3) 300(2) 200(4) 40027. A hole is made at the bottom of the tank filled withwater (destiny 1000 kg/m3). If the total pressure atthe bottom of the tank is 3 atm (1 atm 10 N/m2)then the velocity of efflux is(1) /200 m/s (2 /400 m/s(3) v500 m/s(4) V800 m/srrine water in stremline

Answer»

27) 1atm pressure is equivalent of 0. 76 m of HG.

=O.76*13.6m of water =10.34 m .of water .

V= ✓2gh ,=✓2 *9.8*10.34×3 for 3 ATM.pressure.

V= 24.64m/s
