Odd that they don't want to let anyone know the operating pressure. They seemed to spend an inordinate amount of song-and-dance dodging the "whats the pressure" question.
- __jal 10y agoIt is odd. That was my first question, having used a more traditional (==much larger) one. I have trouble figuring how the cutting speeds claimed jibe with the overall weight of the device. Not calling it out, just saying based on their numbers, that seems like quite a lightweight tank for the kind of pressure used for cutting, for instance, stainless steel.
- DannyBee 10y agoI'm also kinda wildly interested how they keep vibration down, given the operating pressure, etc
- extrapickles 10y agoI wouldn't be surprised if its what a standard pressure washer can do (3k PSI) as they claim to use parts from "other industries". I doubt the pressures are much above 10k PSI as there isn't the power to generate those pressures with a reasonable flow from a standard US outlet.
- foofoo55 10y agoUsing gpm=(hp x 1715 x efficiency)/psi and allowing for 90% pump efficiency along with max 1.93 hp continuous from a 15A 120VAC receptacle, we can simplify the pumping-water-with-a-North-American-receptacle equation to gpm=3000/psi. So 10k psi outputs only 0.3 gpm, 3000psi outputs 1gpm, and 2000psi spits out 1.5 gpm (the latter of which matches the output from the top electric pressure washers).
- Cerium 10y agoAnd since they said that it uses 10-20% the water of a standard shower head... A modern shower head uses about 2gpm, so we are talking about 0.2 to 0.4gpm. That would give us a pressure of about 7500 to 15000psi using your equation.
- cconcepts 10y agoThis is much more realistic. 3k psi will struggle to cut a cake.
- kuschku 10y agoAs someone used to metric, this is probably the msot confusing comment chain I've read yet o.O
- JshWright 10y agoYou don't measure cutting force in cakes?
- cconcepts 10y agoFor those that need it in metric, a cake is roughly equivalent to a scone...
- aidenn0 10y agoAt least in the UK, Her Majesties Customs and Excise tried to measure it in biscuits (which require 17.5% greater cutting force than cakes), but Mcvities prevailed in the courts.
- 50CNT 10y agoWe measure cutting force using a very old baguette held at the Bureau international des poids et mesures.
