One of our Turbine Supplier is not furnishing the Exact Resultant Forces & Moments, when ever we ask from our end they are ask us to do a calcualation as Per NEMA standards. By giving all pressure from us they furnished a Excel Format Calculation. The Excel Calculation Covers the Inlet, Bleed1, Bleed2, Bleed3 & Exhaust, Combined case Caluculations. In that i fed the values just like Trial & Error, where i found in Individual Cases it accepts up to Forces 200kg & Moment 140 kg.m. But in Combined case ALLOWABLE Fc+1.64*Mc<=22Dc gets failed. To satisfy all the cases i got only 40kg & 40 kg.m Forces and Moment. For a 15MW Turbine this kind of load.. i can't believe..

Sorry to ask this in COADE Forum. Because of the Turbine Supplier the Project getting delayed.

The sizes of the Nozzles are as follows

Inlet Size - 150 NB. SCH 120
Bleed 1 - 150 NB. SCH 80
Bleed 2 - 150 NB. SCH 80
Bleed 3 - 150 NB. SCH 40
Exhaust - Equivalent Diameter - 1194.3mm

My question is

1. What the Tubine Supplier doing is rite
[ Request us to do a calculation as per NEMA.. Actually we are the Consultants ] ?

If any one really interested i will send the Excel Calculation what the Supplier sent to us.

Plz Help..
