Thank you lownox for the reply. the door is closing immediately. What happens in that case. what is the procedure for calculating this velocity.
kind regards
I have simple question which I couldn't figure out.
Let say, there is 50 Pa pressure difference continuously between a closed room and outside which is in atmospheric condition. The room pressure is bigger than the outside. When opening the door (Area of door is 3 m2) of room to outside, what...
Hi all,
is there any special software for designing of concrete piping. which gives horizontal laying length, gradient, curve radius, deflection angle, opening length as a result automatically.

Dear David,
Thank you for your reply,
But I guess the values shown in the are for horizontal piping.
What I ask is it the same for vertical piping. is there any constraints other than for horizontal piping.
Hello all,
What shall be the criterias for maximum allowable span for vertical piping.
Is it same for horizontal piping criterias.
thanks in advance

We have underground preinsulated heating and chilled water underground piping, and installed leakage monitoring system for the system.
Beside, customer asks for lekage monitoring system for hot water drainage underground piping. do we really need this system fordrainage piping.
could you...
Thank you for this valuale help. I downloaded the stds you mentioned. I didnt realise any material specification in these sds.
Unfortunately, the customer neither have any specification, nor have any person related to this subject.
the specification of the equipment that shall supply oxygen is...
what is the heat dissipation of electric cable having the size 1000 watt.
Does it neglectd in HVAC calculations or not.
your kind response is appreciated.

COULD ANYONE GIVE ME ANY INFORMATION ABOUT THE DESIGN OF UNDERGROUND PIPELINE CONTAINING OXYGEN USED FOR WELDING IN A SHIPYARD. Q=1000 M3/H.
OP. PRESSURE = 15 BAR.
WHAT KIND OF A MATERIAL TO USE. CAN CARBON STEEL PIPE BE USED.
IS THERE ANY THRUST BLOCK NEEDED.

Hello all,
we have cs, 10", preinsulated, underground piping. It is a hot water drainage pipe.
Is it required holiday testing before backfilling. For drainage piping is this holiday testing mandatory
thanks in advance

yes oil is escaping from the vacuum vent on the floating roof. we check that, the roof is not hanging or stuck anywhere.
escaping occurs at first movements.
We have dia: 92 m, heigth:16 m floating roof crude oil storage tank.
Oil has escaped from the vents (located on roof) during filling and emptying operation of the tank. At first oil starts to pass from the vents, then after oil passing stops.
Could anyone indicate a reason for this.
Have...
Carbon Steel pipe is 12 inch and goes straight about 100m without any bend. It is buried 1 m above the ground. At the end of the route it goes belowground and enters into the building.
Operating Pressure is 10 barg.
Does a expansion loop underground prevents buckling failure. If it is so how...
Do we need an expansion loop or something else for an insulated direct buried underground Carbon Steel piping.
1 meter under tight soil.
Operating temperature is about 100 C.

using ASTM D 341, If I had two values of viscosities at two different temperatures I could fit those values in the above equation and found the fuel constants A and B and then interpolate to find the value of viscosity at a different temperature.
Presently, I know the viscosity of a Heavy Fuel...
