True, In the STEM field engineers use and think in terms of sciences like physics and math.
Answer:
Find the given attachments for complete solution
Answer:

Explanation:
Given that diameter of tube= 20 mm
flow rate = 72 lt/hr
The properties of SAE 30 oil at 30°C


We know that volume flow rate Q= AV

V= 0.064 m/s
Now lets find Reynolds number to check the type of flow


Re=7.18 So we can say that this is laminar flow and we know that pressure drop for laminar flow is given as

Now by putting the values the pressure drop for per unit length


Answer: Symbol rate, Fs = 0.846
Explanation:
The attachment below shows the calculations
