I have coded API 650 nozzle with
24" sch 20 nozzle, nozzle height 1000 mm,
Tank dia 60000 mm, fluid height 18000 mm.
Just to check the effect of fluid height on allowables, i reduce the height to 9000 mm,
keeping all other data same.
The allowables are reduced as shown in caesar error check.
I was expecting to get the allowables more as reduction of tank height would be advantage.
