a garden hose of diameter 2cm is used to fill 1000 litre container in a time of 10 minutes.calculate the flow rate in cubic cm per second .
Answers & Comments
Answer:
Explanation:
Given,
Area, A= 4πd 2 = 4π (0.02) 2
Volume rate of flow,
V˙ = time volume = 60
20L = 310 −3 m 3 s −1
Volume rate of flow = Cross-Section Area × Velocity of Flow
V˙ =Av
v= AV˙
= 310 −3 × π(0.02) 2 4 =1.06ms
−1 =106cms −1
Hence, velocity of water leaves hose is106cms −1 .
