Suppose the tube in the previous problem is kept vertical with B upward. Water enters through B at the rate of 1 cm3 s-1. Repeat parts (a), (b) and (c). Note that the Speed decreases as the water falls down.


Given, area of cross-section of tube A,

area of cross-section of tube B,


Volume of water entering B,


(a)The total volume is equal to area times velocity. Let the velocity in tube B be





(b) Let the velocity in tube B be


As the flow is steady,





(c)From Bernoulli equation we have,
