Posted 5 Mar 2012 I am using directsoft 5.3 but stuck in the calculation of flow rate. formula require a calculation of a number to the power of 1.55 2 ^ 1.55 any idea folks? Share this post Link to post Share on other sites
Posted 6 Mar 2012 Don't know the directsoft system but you could use: log(2^1.55) = log(2) * 1.55 depends if logs are available. Otherwise you are into more long winded calculations like Newton's Method, look at Maths forums for details Share this post Link to post Share on other sites
Posted 9 Sep 2012 I don't believe any of the standard CPU's support either powers or logs......so instead of wasting LOTS and LOTS of time writing code to do such things (it is possible just cumbersome) buy an FO-CP128....its a co-processor basic module.....it should support both (i need to pull the specs from FACTS Engineering....its not listed in the standard AD manual)......at less than $200 and a couple of hours (or less if you drink a couple of 5hr energy's) you should have it done.....that requires you have an available slot to place the module in.... bob Share this post Link to post Share on other sites
