Answer:
In case of 5 m/s:

>
i.e
>0, It means Water will leak out of hole.
In case of 0.5 m/s:

<
i.e
<0. It means air will enter into the pipe.
Step-by-step explanation:
Note:
Values of constant v,f and
can vary according to the conditions. Value taken below are taken from water properties table.
According to Bernoulli Equation: Considering the frictional affects


Where:
is the pressure at other end of pipe(outlet)=0
is the pressure at hole


Above equation will become:



Calculating Re number:

Where:
V is the velocity
D is the diameter
v is the kinematic viscosity of water. Lets consider it
. However kinematic viscosity can be taken according to temperature.
In case of 5 m/s:
Re=

For galvanized iron pipe , Roughness coefficient ε is 0.15 mm

From Moody Charts, At above Re and
, Value of friction coefficient f is≈0.045.
≈9800 N/m^2

i.e
>0, It means Water will leak out of hole.
In case of 0.5 m/s:
Same above Procedure:
Calculating Re:
Re=


From Moody Charts, At above Re and
, Value of friction coefficient f is≈0.052.

<
i.e
<0. It means air will enter into the pipe.
