Answer:
The pressure at this point is 0.875 mPa
Explanation:
Given that,
Flow energy = 124 L/min
Boundary to system P= 108.5 kJ/min
[tex]P=1.81\ kW[/tex]
We need to calculate the pressure at this point
Using formula of pressure
[tex]P=F\times v[/tex]
[tex]P=A_{1}P_{1}\times v_{1}[/tex]
Here, [tex]A_{1}v_{1}=Q_{1}[/tex]
Where, v = velocity
Put the value into the formula
[tex]1.81 =P_{1}\times0.124\times\dfrac{1}{60}[/tex]
[tex]P_{1}=\dfrac{1.81\times60}{0.124}[/tex]
[tex]P_{1}=875.80\ kPa[/tex]
[tex]P_{1}=0.875\ mPa[/tex]
Hence, The pressure at this point is 0.875 mPa
The pressure at this point when energy of 124 L/min of a fluid pass through a boundary of a system of 108.5 kJ/min is [tex]875Kpa.[/tex]
Pressure can be regarded as a force which can be applied perpendicular to the surface of an object.
We can determine the pressure using the formula;
[tex]P=Fv[/tex]
Where P= pressure
F= pressure at a point
V= velocity.
We were given Boundary to system [tex]P= 108.5 kJ/min,[/tex] which can be converted to KW as; [tex]1.81KW[/tex]
We were given Energy as [tex]124L/min= (124/60*1000)= 0.00207[/tex]
Then we can substitute into the given formula as;
[tex]1.81=F * 0.00207[/tex]
[tex]F= \frac{1.81}{0.00207}[/tex]= 875Kpa
Therefore, pressure at this point is[tex]875Kpa.[/tex]
