Answer:
The friction factor is 0.303.
Explanation:
The flow velocity (), measured in meters per second, is determined by the following expression:
(1)
Where:
- Flow rate, measured in cubic meters per second.
- Diameter, measured in meters.
If we know that and
, then the flow velocity is:
The density and dinamic viscosity of the glycerin at 20 ºC are and
, then the Reynolds number (
), dimensionless, which is used to define the flow regime of the fluid, is used:
(2)
If we know that ,
,
and
, then the Reynolds number is:
A pipeline is in turbulent flow when , otherwise it is in laminar flow. Given that flow has a laminar regime, the friction factor (
), dimensionless, is determined by the following expression:
If we get that , then the friction factor is:
The friction factor is 0.303.
<u>Explanation:</u>
Task 1 time period = 200ms, Task 2 time period = 300ms
Task ticked = → 5 times
Task 2 ticked = → 3 times
At 600 ms → 200ms 200ms 200ms
300ms →
Largest time period = H.C.M of (200ms, 300ms)
= 600ms
