I can't agree w/ a diameter of 1 cm. ----- Original Message ----- From: Alan J Fletcher To: vortex-l@eskimo.com Sent: Tuesday, September 20, 2011 6:49 PM Subject: Re: [Vo]:Calculations for 1 MW plant. + Time to Drain the eCat

The running time on video is more like 1:20, still greater than drain time for 2 atm, showing there is less than 2atm pressure. But since we don't know for how long the draining continues we dont know how much less. Since the E-Cat is open to atmosphere (by report) we can assume the pressure is 1 atm. Also 1/4 cm seems a bit small for the orifice and drain time would seem to affected by height of water column. I corrected the run time. The time to drain goes as 1/orifice_area * sqrt(column_height) 1/4 is the radius -- 1/2cm diameter At 02:50 PM 9/20/2011, Jouni Valkonen wrote: Considering Akira's temperature graph, we can take that draining took about 5-7 min. That's about 23:15 to 23:22 Hmmm .... since the outlet is still open cool air will be sucked past the temperature probe, cooling it. When it's completely drained this flow will stop, and the thermal mass will cause the air to heat up again.
