Calculating T#1-InTrans
The value of T#1-InTrans is as follows:
(d)
Calculating T#1-OutTrans
The value of T#1-OutTrans is as follows:
(e)
Calculating T#1-Free_I/OCycle
T#1-exsoft is calculated with the calculation formula for T#1-Free_I/OCycle.
There are 18 NX Units.
Based on the calculation results for (c) and (d), the values of T#1-InTrans and T#1-Out-
Trans are as follows:
T#1-InTrans = 156.12

T#1-OutTrans = 47.38
