Vacuum pressure 

Why we use 0 to -760 hg range in vaccum guage

*Abs. Pressure= Atm. Pressure + Positive gauge pressure[Atm. Pressure is taken as datum line] **Atm. Pressure= Abs. Pressure + Negative gauge pressure ( or Vaccum Pressure)[ Zero Abs. Pressure is taken as datum line]

Please comment about leaving enough specs from keept product, with a vacuum sealer machine. it's necessary? But why west pe bag?

Sir,negative air presser pressing karta hai ya fir air ko kichke vaccume create karta hai

Good sir , Nice class. We want class on flow , density....

Kya hum ejector ya vacuume pump ke through condenser me 100 kilo Pascal se jyada negative pressure yani -200 kilo pascal create kar sakte hai? Please karan sahit reply kijiye... Koi bhi reply kar skta hai

Gud evening sirji Plz suggest how to calculate a flow rate of vaccum preasure

760mmhg pe pressure???????btao

sir ji vacuum ki unit me Hg kyun use krte koi or kyun nahi

Please actual data of aneroid barometer ka dikhao Kitna work done hota hai jo sui ko ghuma deta hai ? Kitna kaam ek aneroid barometer karta hai Per milibar changing per degree of celcious Agar hum 1000000x bigger models ko use karkey ek TW energy electricity turbine ko chala saktey hain kya ?

Stream pressure ko kg/cm squire me badalne ka video banao sir

Sir kl ka exam ka liya kuch important bta doo..

Pta nahe iss bai k dimagh main kia chal raha hy pr iss ki baty sare mery sar k opr sy guzar rahe hy wo 120km/hr sy

I think its gauge

🙏🏼🙏🏼🙏🏼🙏🏼

Pata nhi kya btana chah raha hai

Vacuum ka spelling to thik likh lete sir
