Penetrating finishes are absorbed by the wood and dry inside the wood. Interior wood stain is used to accentuate the grain in natural woods or plywood while still adding some color. While wood stains offer some level of protection on wood, it's recommended to use stain in combination with a surface finish.
Answer:
Power output, 
Given:
Pressure of steam, P = 1400 kPa
Temperature of steam, 
Diameter of pipe, d = 8 cm = 0.08 m
Mass flow rate, 
Diameter of exhaust pipe, 
Pressure at exhaust, P' = 50 kPa
temperature, T' = 
Solution:
Now, calculation of the velocity of fluid at state 1 inlet:




Now, eqn for compressible fluid:

Now,




Now, the power output can be calculated from the energy balance eqn:



Answer:
The volume percentage of graphite is 10.197 per cent.
Explanation:
The volume percent of graphite is the ratio of the volume occupied by the graphite phase to the volume occupied by the graphite and ferrite phases. The weight percent in the cast iron is 3.2 wt% (graphite) and 96.8 wt% (ferrite). The volume percentage of graphite is:

Where:
- Volume occupied by the graphite phase, measured in cubic centimeters.
- Volume occupied by the graphite phase, measured in cubic centimeters.
The expression is expanded by using the definition of density and subsequently simplified:

Where:
,
- Masses of the ferrite and graphite phases, measured in grams.
- Densities of the ferrite and graphite phases, measured in grams per cubic centimeter.


If
,
,
and
, the volume percentage of graphite is:


The volume percentage of graphite is 10.197 per cent.
