the best guess you can make is 24hr actual variable (times) ksol/sec... should get you in the ballpark of what it could make in 24 hours.
oki but can u help me to make a calculation example with the above paraneters?
If you are asking if there is a way to calculate how much *BTC* you will earn given a certain amount of Equihash* hashrate, then there isn't one, really. You can sort of estimate your earnings by seeing how much your hashrate will make of any one coin that uses your algo then convert that to BTC yourself, but since there is a delay - oftentimes a considerable one - between when you mine the coin and when it is converted to BTC this is only good for very rough estimations. And by "very rough" I mean "+/- 30%" (though in my experience one never sees the positive end of that range... ahem).
* - or any other single algo
