erobz's latest activity

In a real system with viscous losses I wouldn’t be able to tell until I had some real system/fluid properties to fiddle with...

This system has a static pressure pre charge of 200 kPa. Turning on the pump will accelerate flow through the pump via pressure...

Agreed - I only said "according to the calculation". The pump can only generate a flow by raising pressure. However, once a...

See my latest reply to @haruspex. Post in thread 'Bernoulli vs real life experiment'...

In my opinion “the system” must be precisely tuned to achieve relative vacuum in the contraction. For instance, If it’s jetting to...

a) how is pressure being applied if the pump is off? b) ##v_1## appears out of thin air, where did you get it? I’d like to explore...

They are bone, so pretty sure they sink and are relatively impermeable over the short timescales needed to make the measurement.

This will be a quick duration dip (done slowly as not to make waves), it won't be soaking. Just enough time for the water level to...

Thank you, that technique would make precision adjustable. Also, this measures the volume directly; skipping a computation step and...

My idea is that I want to use immerse Whitetail Antlers in a fishtank to measure their volumetric displacement (the Boone and Crockett...

You know what. Never mind. When I try to solve problems anymore, I get an almost nauseated with trembling anxiety, hyperactivity...

erobz: catch it

Well the liquid mass in the buggy must be accelerated from u to v inside the buggy? So it feels like an inelastic collision should be...

I'm trying to work this out from a Fluid Mechanics perspective with the Momentum Equation and Mass Conservation: $$ \sum \boldsymbol{F}...

Here's another way to look at it. There are no external forces on the large mass M. A small mass, m, is fired at a known speed (the...
