First of all please do understand that ASME PTC-10 is only a "thermodynamic performance" test criteria, means it focus on process / operation related performance only, expected from specific machine. It has nothing to do with mechanical balancing or any other mechanical related issues. Please refer ...

When ever we talk about limit of velocities of any fluid, we always refer to allowable 'rho*v2' limit. Here rho is the density of fluid at flowing conditions and v is velocities. In a general practice following rhoV2 limits are acceptable, (keep that in mind that these are best practices ONLY).

hussain, let me re clarify that type II test is not as per actual operating / design conditions. So that is the major deviation. ASME doesn't allow any other deviation in type II tests in particular. The table you are referring to is for the permissible deviations of machine mach number, reynolds ...

wao thats a complex one. Isn't it some what the same as of auto fuel to air ratio controller in boilers. As frontend consists of calculation blocks, don't you think about this calculations will go into infinite loop. i.e. from comparator to the PID setpoint, then form from PV to comparator and then ...

ASME PTC-10 is an extensive document dealing with the testing of centrifugal / axial compressors / exhausters. This document specified two type of test as follows;
Type I - It covers situations in which process gas and test gas are identical within certain predefined and agreed limitations. So that ...

What major factor contribute in SIL and how to determine SIL level of any system as a whole. How number of SIFs impact SIL and how anyone can define LOPA in view of SIL?

We have liquid propane spherical storage vessels and we use following empirical relation;
V = 3.1415 x ((R/2 x H^2) - ((H^3)/3)))
where
R = Radius in ft
H = Liquid level in ft
V = Liquid volume in ft^3

Hope this may help you in finding the relation for horizontal vessel

I second you guys, but qasim if you want to do it yourself you can use following references for fire and flare radiation impacts;
API-RP-521 "Guide for Pressure Relieving and Depressuring Systems"
API-931 "Manual on Disposal of Refinery Wastes"
GPSA Engineering Data Book.

Hope this may help you.

Thats a very critical part of design. My friend I would suggest you to go thru API-RP-520 and API-RP-521 for sizing, selection and installation of such pressure relief and protection devices. I can guide you thru if you can share some process data.

I am quoting from a very renowned design engineering practices of an oil & gas EPC and operating company, as I remember;
"If the compressor bypass control line is taken downstream of the discharge cooler (after discharge check valve), an additional hot gas bypass line upstream of the discharge check ...
