these values can not be compared
these values can not be compared
(OP)
Hi, first, I would like to say i am very new for Mathcad. My questions might be very easy for someone.
You can see an error in my file, the attachment.
I've tried to calculate drag force at each water depth.I can calculate current at each water depth. But when i tried to use the results(current) in another question to find force, I got "these values can not be compared".
I know that there is something about array or others but i don't know how to fix it.
<After i calculate the force, i still need to use the force in further equations. this would be the same problem how to identify array for the eq.>
Anyone please gives me an advice?
another question, how i can adjust space between each row(equation boxes)?
Thank you so much.

RE: these values can not be compared
do the following:
i:0;3000 d[i:-i
current(d):if(-40<=d<=0,(-0.5*(-d)/400)+0.7,0.2)
drag[i:-1/2*cd_wcp*area_wcp*rho*current(d[i)
where
: is the keystroke for the := assignment
[ invokes the array subscript operator
