Question

Example 4.1. A hose pipe used for gardening is
ejecting water horizontally at the rate of 0.5 m/s.
Area of the bore of the pipe is 10 cm². Calculate
the force to be applied by the gardener to hold
the pipe horizontally stationary.​

Answer 1

Answer:

mark me the brainliest

Explanation:

F = density × area ×velocity

2

Convert V to m/s:

20/100=0.2

=0.2m/s

Density of water =1000

m

3

kg

Convert the diameter length to be in meters :

20/100=0.2

Area of the outlet :

3.142×(0.2/2)

2

=3.142×0.1

2

=0.03142

Doing the substitution :

F=1000×0.03142×0.2

2

=1.2568

Answer 2

Answer:

1.2568
