InFig. 105 the cylindrical tank, A, has a capacity of 100 gal-lons of water under a pressure of 10 pounds per square inch,due to the weight of the piston. Neglecting the weight ofthe water, the pressure gauge will record a pressure of 10pounds. When the valve is opened the water will be dis-charged at therate of aboutone gallon perminute, under apressure of 10pounds persquare inch, sothat at this rateit will require100 minutes toempty the tank. A similar tank, B, has a capacity of 10 gallons of water undera pressure of 10 pounds per square inch, due to the the weight of the water, the pressure gauge willrecord 10 pounds also. The diameter of the pipe is the samesize as in tank A, and when this valve is opened the water willflow out at the rate of one gallon per minute under a pressure looS-o-flg^Uwfc \o5-cM>v^2^vJi.

In both tanks the pressure andthe rate of flow are the same, but tank A will maintain the current of sv Cc£CA Zip â¬UU>
