We optimized the other two important components of the catalytic water heater, the venturipipe and nozzle.
文丘里管和喷嘴是催化燃烧热水器的关键组分,实验中对二者进行了优化。

An automatic topdressing system was designed on the base of the principle of hydrokinetics using energy of static pressure for pipe irrigation and the feature of Venturipipe in solar greenhouse.
The paper also discussed the structure parameters and the flow-speed of the throat-pipe and water volume needed and pressure loss of the Venturi tube in the new dusting system.
