'geissele' Read with interest your comments on FALK giving ISO codes on splash and filtered systems. Why would one run a splash lubricated box four times dirtier than a filtered box? I've seen 1500 HP FALK boxes (bearings) fail in two years which is the result of running a box at ISO 23/20/18...

Are you still looking for information?? I wrote a paper on this subject for a large Mining Group and will e-mail you a copy of this if you like.

We have a series (80 units) of hydraulic jacks made by Firestone (rubber) and use a water glycol mixture to power the jacks. Could we use an oil/water emulsion - similar to that used in mining props, which is a 5% oil to 95% water mix? Temperature never reaches freezing and the system would...

Thanks butelja, I work with pipe frictions a fair bit of my time but drew a blank on an open trough calc. Simple when you know how!! Thanks again icw

Need to allow water to flow in an open stainless steel U shaped trough tilted at an angle of 1:5 at a flow rate of 8 litres per second. Question: What are the profile dimensions of this trough which is 2 metres long? or better still, what is the calculation?

Undersized ..... Here are some basic calculations: 1. Pool capacity = 13,500 gallons 2. Flow rate thru Sand Filter should not exceed 5 to 8 gpm per square foot surface area. 3. Should circulate all water approx 6 times per day. 4. At 45 gpm this will take about 30 hours per day (a bit of...
