We now know that we have to install a ventilation system that could generate roughly 270 CFM for the said kitchen from the calculation above. If we plan on building an energy-efficient house with a centralized ventilation system, it would be best to work out the CFM requirement for each roo...
Another example are bathroom exhaust fans. When sizing a bathroom fan, you need to take into account 8 ACH. You can checkhow many CFM for the bathroom exhaust fan you need here(both the calculation and application of 8 ACH). If anything is unclear here, you can pose the question in the...
We’ll explain the calculation first, and summarize the calculation in the shorter step-by-step process at the end of this chapter: Calculating Bathroom Fan CFM By Hand Bathroom exhaust fans can produce anywhere from 40 CFM to 350 CFM of airflow. That is the very airflow that needs to be...
The wastegate is on the exhaust side of the turbo. The exhaust gas is routed around the turbine when the wastegate is open and the high pressure gas is directed across the turbine when it is closed. A bigger turbo will usually do this more efficiently since the actuator ...
ECU CHANNEL A INPUTS Channel A receives via bus network: - The anemometric parameters for thrust calculation from the Air Data Inertial Reference System (ADIRS), - The A/C command signals from the Engine Interface Unit (EIU) for engine control. Each ECU receives a single hardwired signal ...

By this I assume you mean that you have a fan to force combustion air into the unit, but do not also have an exhaust fan. If so, then be careful about the "exhaust rate" you use in the purge calculation. Be sure it's correct. Such units are notorious for having highly variable ...
Thanks for your input. Your calculation of power output and calculation with equation suggested by Hermit47 matches very closely. I understand there is no possibility other than increasing the pressure for getting more power out. Could you suggest what dictates the Exhaust pressure of a turbine....
This is the formula for ACH (air changes per hour): On this topic, we have published an insightful article about how to adequately size a bathroom exhaust fan. This calculation includes knowing bathroom dimensions and implementing the 8 ACH rule of thumb for bathrooms. You cancheck this articl...
