Re: central air pressure

HEY RAJ

THUM-UP............................

WELL THIS IS YOU ARE TALKING ABOUT SOMETHING WHICH COMES AFTER DOING PRACTICALITY OF THE THINGS. BUT THERE IS GENERAL VIEW THAT IF YOU INCREASE PRESSURE THE VELOCITY WILL DECREASE . CAN U B MORE SPECIFIC TO YOUR STATEMENT

CHEERS

Re: central air pressure

Dear Rahul,

Could you please send me your e-mail ID ? I will send you a graph which is drawn between nozzle prssure and tip velocity.

Regards,

Re: central air pressure

Hi friends

I hope that both of you are correct. But only the conditions are different.

For the same flow, as in the case of venturimeter, when the cross sectional area is reduced, the velocity( or dynamic pressure) will increase and the static prssure exerted on the side walls  will be reduced

For the same cross sectional area like ther tip area in the burner nozzle, when the static pressure is increased by means of increasing the primary air fan speed, both the velocity(or dynamic pressure) as well as the flow will be increased.

Regards

Vinayak

Hey mr. Sahu; Can you send to me a copy of that graph which is drawn between nozzle pressure and tip velocity!
