Now, I KNOW you were all wondering.. so I found out for you

Does the power usage increase when fat people get on it?

Is this a ploy for more 'best mod' votes?

Hmmm - putting a serious hat on..

No, because the undertall person will compress the air in the castle, but the stored energy will be released when he/she bounces (ignoring the losses due to the fact that it will be non-adiabatic compression.

However if there is a pressure relief valve, that energy will be lost.

Of course, the excess pressure could be vented back through the blower, so it would take less energy momentarily, but then take more as it reaches the steady state when they get off.

However I hope Zak has set up instrumentation on the castle so that he can correlate power consumption and castle internal pressure over time, while monitoring the mass of all those bouncing on it!

Of course he might have just been distracted by mopping up the after-effects of too rigorous bouncing after an excess of birthday cake

now THAT is a proper question... and I had one to hand.

Well.. I didn't but I DID have a 6'2" 16 stone brother in law ready to jump up and down in it....

and remarkably, even with the air pressure being rammed back up the pump's turbine... no... it didn't flutter more than a few W.

clever thing

Why would you even want to know this?

why?

why not?

I knew a few of the nutters here would find it funny....

welcome to the forum by the way.

Has anyone sustained injury on the bouncy castle bad enough to cause a clicking neck ?
