While driving your rental car on your vacation in Europe, you find that you are getting 8.8 km/L of gasoline. What does this val
1 answer:
Answer : The value correspond to in miles per gallon is, 20.6976 mile/gallon
Explanation :
The conversion used to convert kilometer to miles is:
1 km = 0.6214 miles
The conversion used to convert liter to gallon is:
1 L = 0.2642 gallons
Thus,
1 km/L =
1 km/L = 2.352 mile/gallon
As we are given that 8.8 km/L of gasoline. Now we have to convert it into mile/gallon.
As, 1 km/L = 2.352 mile/gallon
So, 8.8 km/L =
= 20.6976 mile/gallon
Thus, the value correspond to in miles per gallon is, 20.6976 mile/gallon

Answer:
The estimated feed rate of logs is 14.3 logs/min.
Explanation:
The product of the process is 2000 tons/day of dry wood pulp, of 85 wt% of cellulose. That represents (2000*0.85)=1700 tons/day of cellulose.
That cellulose has to be feed by the wood chips, which had 47 wt% of cellulose in its composition. That means you need (1700/0.47)=3617 tons/day of wood chips to provide all that cellulose.
Th entering flow is wood chips with 45 wt% of water. This solution has an specific gravity of 0.640.
To know the specific gravity of the wood chips we have to write a volume balance. We also know that Mw=0.45*M and Mc=0.55*M.
The specific gravity of the wood chips is 0.494.
The average volume of a log is
The weight of one log is
To provide 3617 ton/day of wood chips, we need
The feed rate of logs is 14.3 logs/min.
