I'm a student. I'm simulating the production of ammonia from nitrogen and hydrogen as shown in Figure 2 and want to know the costs. But found that the value could not be viewed and encountered an error as shown in Figure 1 if you want more data or know how to solve pls answer my question.

cooler :

"ERROR> 'HE - 6' SPECIFIED AREA DIFFERS FROM CALCULATED AREA BY >10 PERCENT.

Heat transfer area INPUT: 1.105 CALC: 5.236 SF"

Turbine :

"ERROR> 'TUR- 94' ACTUAL GAS FLOW RATE INLET IS OUT OF RANGE

ERROR> 'TUR- 94' DESIGN GAUGE PRESSURE INLET IS OUT OF RANGE

ERROR> 'TUR- 94' DESIGN TEMPERATURE INLET IS OUT OF RANGE"

I think this software allows the user to override the calculated equipment sizes manually to get cost results. A few suggestions in no particular order: Enter more data for the equipment to satisfy the software. Change data to match the calculated sizes. Ignore the software costs for these pieces and use another method for costs, Find dimensions that work in the software and scale the calculated result to estimate costs for the dimensions you really need.
