    B10 life meaning

    We are using the same standard for reference. Only confusion is "B10 - EXPECTED TIME AT WHICH 10% OF THE POPULATION IS PREDICTED TO FAIL" means scenario A (or) B. Thank you.

    B10 life meaning

    Hi Happy new year! It is for my understanding only. My colleague statement is scenario B. My point is scenario A. We are dealing with pneumatic products where life of a product specified in terms of distance / cycles. We are already practicing reliability and determining B10 life for our...

    B10 life meaning

    Hi What is mean by B10 life. For example, B10 life is 1000 hours calculated from physical validation of part. Scenario A: Which means 10% of population may fail BEFORE 1000 hours. In a population of 100 parts, 10 parts may fail BEFORE 1000 hours. 10 parts failure may be at. 100, 200, 300...

    Profile tolerance for outer rectangle surface

    I am using ASME Y14.5:2018 standard. I have seen examples for CF as below. Is it possible to use CF as below? As per ASME Y14.5:2018, para 3.10 and 3.11 CF defined as "two or more interrupted features". Till date I thought of interrupted by material removal. My bores are different in size...

    Profile tolerance for outer rectangle surface

    Can you provide any reference standards for this? Thank you for the suggestion. In whats app messaging application software, if we mentioned @ symbol the list of contacts will be displayed and the concerned person will be notified separately. Here I would like to mention that the reply is to...

    Volumetric flow calculation

    Thank for the input. Below are my observations. Density is function of pressure and temperature. Standard temperature and pressure: 15 degree Celsius and 101325 pa. Normal temperature and pressure: 0 degree Celsius and 101325 pa. https://www.controlandinstrumentation.com/flow/standard.html...

    Volumetric flow calculation

    How did you get this number? Density for air: 1.29 Kg/m3 I am unable to get your point. Can you elaborate with numbers? Thank you How did you get this number? or any formula to calculate? Thanks with Regards, Sathish Rosario

    Volumetric flow calculation

    I am clear with this concept. Can you please explain with numbers. Say, my gauge pressure is zero barg. Standard atmospheric pressure is 1 bar. Hence, absolute pressure = 0+1 = 1 bar. right? (Earlier I have mentioned 2 bar as absolute) Can you explain the calculation steps? My calculation...

    Volumetric flow calculation

    @LittleInch Even though the tank pressure is 11.5 barg, we are controlling the input pressure to test specimen by a regulator. Test circuit: Air source ---> Tank ---> Pressure gauge ---> Filter ---> Regulator ---> Pressure gauge (P1) ---> Test specimen ---> pressure gauge (P2) ---> Ball...
