    Calculating Total Electric Power Input kW 3 phase Motor

    @edison123 Calculations at RUNNING conditions Output KW = √3 x Input voltage x Input current x power factor x efficiency = √3 x 0.38 x 320 x 0.87 x 0.959 = 175.7 KW Input KW = Output KW / Efficiency = 185/0.959 = 183.2 KW as @waross indicated efficiency is load dependant but real value I...

    Calculating Total Electric Power Input kW 3 phase Motor

    @waross My electric foreman simply stated this (running Electric consumption): 380V x 320A / 1000 = 121.6 kW

    Calculating Total Electric Power Input kW 3 phase Motor

    I am attaching motor nameplate (its an Cl2 compressor) The running ampere on the meter (it varies with throughput) is now 320A According to this post (https://www.eng-tips.com/threads/actual-work-380v-vs-460v.91809/post-344509) , total electric kW input will be =1.732 x 320 Amp x 380 Volt x...

    Valve Characteristics relationship with pipe length

    I have found x2 comments made on the use of Equal% & Linear control valves on LinkedIn I cannot understand the relationship between length of pipe & valve characteristics? Secondly per my operational experience the 2nd point is not true as even at very long Cl2 lines I can see Equal%...

    Coupling Degeneration [multiple pumps affected]

    I am attaching images perhaps someone can provide insight as to what may be the reason & how we can avoid it. The pump in picture are brine pumps as well as vacuum pumps [both are provide by HB company]

    Liquid Ring Compressor Polytropic Head Calculations

    I am attaching pdf & SMath sheet that provides a x3 page calculation & perhaps someone can review it. The background is I have a liquid ring compressor that vendor provides performance curve tested with air media while actually it will be used for H2. From this data I have calculated polytropic...

    Process Safety regarding gas seal water supply

    U bends may get their liquid traps blown out if velocity is not well controlled. I am unable to understand this

    Process Safety regarding gas seal water supply

    @ LittleInch I get the impression I'm annoying you and your answers are coming across as a bit "spiky". You might not like having your design being questioned, but we're all just trying to help here. Haha. Sir English is not my native language so I can write what I think is correct but its...

    Process Safety regarding gas seal water supply

    So the CL tank should be fed by a separate tank or a separate water line. Only if there are very good reasons not to ( and cost isn't one of them) It is not possible What length is that? Exactly 5m as well? As you can see in the illustration it is (dip leg) exactly 5m Loose less than a metre...

    Process Safety regarding gas seal water supply

    I think a U-Bend at feed water line can be regarded another safeguard
