Hi there,

 

I was hoping someone would be able to jog my memory on how to compute this system of equations.

 

In this equation we're finding tc.

 

Please note: tf was found to be 2.9

 

 

I appreciate your time,

 

Evan

 

EDIT: tc was found to be 4.8

If tc/tf =max(3.3-1.1*0.104-0.34*4.5, 1.1) then tc/tf = max( 1.6556, 1.1), since 3.3-1.1*0.104-0.34*4.5 = 1.6556;  so tc/tf = 1.6556

 

Multiply both sides by tf:    tc = 1.6556*tf  or  tc = 1.6556*2.9 or tc = 4.8012   or tc ≈ 4.8
