Ok that certainly sorted it. Thanks again 🙂
i’m still kinda confused as to how in this line
0.1683 = Keu + (0.75 x Keu x 1785/1400) – (0.75 x 0.0476 x 1785/1400)
you’ve split the expression and multiplied both sides by 0.75
but ill just follow and learn it as you’ve done it.
Thank you so much for the help.
