Introduction
Fossil fuels
- Main Energy Source
- Causing global warming
- Being exhausted
→ need
alternative energy
Hydrogen is one of well-known clean energy source.
Several technologies are already available in the marketplace for the industrial production of hydrogen.
Hydrogen can be produced from a variety of feedstocks.
A variety of process technologi
of impeller of pump.
- Position of pump is higher than fountainhead.
Solution
- Make suction head and friction loss small.
- Make the velocity of impeller small.
- Install the pump lower than fountainhead.
- Use double suction pump.
- Control the water pressure inside tube higher than vapor
pressure.
- Make suction caliber big.
- Install pump more than two.
임의의 온도에서 기-액 평형 데이터를 얻기 위해서 응축액 (vapor)의 질량을 비중병을 이용해 측정 기록한다.
