Explanation:
Answer:
they require more testing in real-word conditions
Explanation:
One of the biggest reasons for this very slow uptake of hydrogen vehicles is the existing infrastructure. ... The sceptics' first argument against hydrogen vehicles is that they're less efficient than EVs are. Because hydrogen doesn't occur naturally, it has to be extracted, then compressed in fuel tanks.
Answer:
The total kg from the mixer: 
Evaporated water: 
Jam produced: 
Explanation:
Step by step:
1) Kg of mixture from the mixer
It says that crushed fruit is added to the mixer with the sugar and pectin.
The fruit added is 1000 kg
The sugar added is 1.22 kg sugar/1 kg crushed fruit:

The pectin added is 0.0025 kg pectin/1 kg crushed fruit:

The total kg from the mixer:

2) Evaporated water
To calculate the evaporated water it's important to have in mind that the mix goes from a concentration of 14 wt% to 67 wt%. This difference is because of the evaporated water. So:
Initial: 1000 kg of fruit with 14 wt% of solids

<em>This amount of solids is constant </em>
Final: The mass of solids is the same but now it represents the 67 wt%

and


3) Jam produced
