Homework Statement


A pipe has area 4 cm2 and is connected to sprayer that has 4 holes each of 0.5 cm2. If the speed of water in pipe 2.5 m/s, the volume of water that comes out from each of the holes in 1 minute is ... liters
a. 0.1
b. 0.6
c. 1
d. 6
e. 10

Homework Equations


A1v1=A2v2

Q = V/t = Av

The Attempt at a Solution


Q = Av = 4 cm2 x 250 cm/s = 1000 cm3/s

V = Q.t = 1000 x 60 = 60 000 cm3 = 60 liter

V in each holes = 60 / 4 = 15 liters ?

My answer doesn't even close to the choices...:cry:

Where is my mistake? Thanks
