Would if be possible to add entropy to the steam tables however? It would be very useful. ### 5/5 — The best app *2015-11-12* It's free and very useful with complete category. ### 5/5 — Good app *2014-03-18* This is a good app for steam calcs ### 1/5 — Questionable results with IP units *2014-01-13* Tested pipe sizing by velocity on a small unit heater I'm designing. 70 psig 120 lb/hr 6000 fps max 500 ft Result: Steam temp = -316 deg F 1/8" nps pipe 497 fps dP=3043 psi I imagine the negative steam temp is a big part of the problem, but the pressure drop massively exceeding the pressure is big cause for concern too. I'll hold on to the app for a couple weeks to see if they release an update. ### 4/5 — Very handy......!!! *2013-07-02* Nice handy tool for engineer. ### 5/5 — Exelente Apps *2013-06-10* Eficiente...
