Please , can anyone tell me how to calculate and define pressization unit components according to the following information :
1- System total volume
2- Static pressure
3- Working system pressure
and that's all information i have

Thank you

engwaseem,
Your question not very clear. Do you mind to elaborate more

- what is your purpose of your question ? looking for definition ? to understand the relationship between them ?...

- is your system gas, or liquid or solid or mixtures...

too wide to guest your question

hai waseem,

provide full system details

Hi and thanx for being interested in my question, sorry I 've been away for a while, anyway i'm looking for a formula to calculate pressurization unit parameters for A/C systems, liquid: water, and i have only the following info: -water system volume -working pressure -fill pressure.

thank you

Dear Eng Waseem,

For 10 ft height of building the pressure rating is 4.33 psig.

I dont know much abt this.I am also in search of the design of pressurization unit.

Pressurization unit is just to make up the pressure in the chilled water system. the design of the pressurization unit is based on mere assumption. Take 2 to 5% of total system volume as the flow of the pressurization unit.... Head will be the sum of static pressure, working system pressure and for a 10% factor of safety.

Eng Wasim... hope this will satisfy you... if not we will together search for a software which will help us to design the pressurization unit
