The rest of the wood was burned into gases of equivalent weight.
<u>Explanation</u>:
The rest of the wood was burned into gases of equivalent weight.
- When wood is burnt in the open air, with the help of oxygen and heat, it is transformed into carbon dioxide, water vapor, and ashes.
- Ignition and combustion of wood mainly depend on pyrolysis which is also known as thermal combustion.
- The loss in weight of the ashes is due to the fact that gases and water vapor are also formed due to the combustion of wood.
Answer:
The mean velocity is 13 ft/s.
The Reynolds number is 88,583 and it is dimensionless.
Explanation:
We have water flowing in a pipe of 1.05 in diameter.
The density is ρ=62.3 lb/ft and the viscosity is 1.2 cP.
The mean velocity can be calculated as
The Reynolds number now can be calculated for this flow as
being ρ: density, u: mean velocity of the fluid, D: internal diameter of the pipe and μ the dynamic viscosity.
To simplify the calculation, we can first make all the variables have coherent units.
<em>Viscosity</em>
<em>Diameter</em>
Then the Reynolds number is
