Broken yellow b/c you can’t pass on a double solid yellow
To solve the exercise, it is necessary to apply the concepts related to the conservation of the energy flow given by Bernoulli and the equation of head loss in the pipe for laminar flow. Through them and the calculation of the flow we can identify the flow rate of oil.
Bernoulli is defined by,
Where,
P = Pressure
= Density
z= Datum height
V = Velocity
g = Gravitaty constant
= frictional head loss in the pipe
There is no change in the final height datum nor initial speed. So,
Re-arrange to find the head loss,
In the case of the head loss in the pipe for laminar flow we have that
Equation we have,
At this point our values are given as,
Therefore,
Finally the discharge is given as
Where,
A= Area
V = Velocity
That is equal in cm^3 per hour as,
Therefore the flow rate of oil is 4521cm^3/h
Answer:
The branches of physics are;
- Classical physics
- Modern physics
- Nuclear physics
- Atomic physics
- Geophysics
- Biophysics
Explanation:
Physics is a branch of science that studies nature, properties of matter and energy. The subjects in study are; mechanics, light, heat, light, sound, electricity, properties of atoms and magnetism.
The common branches are;
- Thermodynamics which that studies heat, how it is transferred and effects
- Sound that studies production, properties and application of sound waves
- Light that deals with properties,pysical aspects and objects that utilize light
- Electricity and magnetism that studies charges, their effects and relation with magnetism
- Classical physics that studies laws of motion and gravity
- Modern physics that study theory of relativity and quantum mechanics
