Need calculations for wall climbing RC car

AI Thread Summary
Calculating the suction pressure for a wall-climbing RC car involves understanding the airflow requirements of the venturi system and the volume of the suction cups. Key factors include pressure, area, and the coefficient of static friction to determine if the car will adhere to the wall. Selecting appropriate motors for driving the suction fans is also crucial for effective operation. The equations for hovercrafts may not directly apply due to the unique mechanics of the toy. Accurate calculations will ensure the car's performance on vertical surfaces.

I am trying to imitate the Airhog zero gravity climber

can someone please help me regarding derieving equations for the suction pressure required and regarding selection of motors for driving suction fans.
the toy basically uses an air venturi system so i am a bit unsure that the equations of a hovercraft would be applicable.
please help me out.

can someone answer my query
 
Hmm.. I think that the volume of the suction cups will need to be calculated into the airflow requirement of the venturi. Other than that, you have pressure and area to find force and you'll need a coefficient of static friction to know if it'll slide down the wall.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
