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 advantage to using a rosebud tip is that it expands the flame temperature over a wider area vs using a #0 size tip.

Answer:By the sympathetic branch.
Explanation: The two branches of an autonomic systems are the Sympathetic branch and the Parasympathetic branch.
The sympathetic branch alone both relaxes the bronchial muscles to open the airways and allow more airflow, as well as increases the heart rate to move blood to the muscles faster.
