Figure below shows a liquid being pushed out of the tube by a piston having area of cross section 2. 0 cm 2 . The area of cross section at the outlet is 10 mm 2 . If the piston is pushed at a speed of 4 cm s -1 , the speed of outgoing fluid is_____cm s -1
Text Solution
Verified by ExpertsThe correct answer is:
80
(80)
The given data is
A 1 = 2 x 10 -4 m 2
A 2 = 10 x 10 -6 m 2
v 1 = 4 cm s -1
Using equation of continuity which is a conservation of mass principle,
A 1 V 1 = A 2 V 2
= 80 cm s -1
