Hello,
I have been asked to comment on an existing fire fighting system recently built. It consist of 4 hydrants in a tunnel where hydrants are 120 m apart. The problem they are facing is that they have install fire hose reels of 30 m in length which have 30 m [hose length] + 10m [throw]= 40 m...
G'day,
I was asked to design a firefighting system for a labor Camp sonsisting of 28 portable cabins (steel structure 12m x 3.5m x 4m. The area of the camp requiring a fire fighting system to be implemented will cover an area of 19081 m2 with a total of 204 cabins consisting of 12 persons each...
Hello All,
I was asked to design a high end cooling system for an overhang connected to a palace. this Overhang structure is 40meters x 20meters and is open area from 3 sides and meant to provide shade at the building entrance. the temperature can reach 50 degc in the summer and it's a dry...
Hello All,
I am currently studying all possible solutions to stop the leak in the firefighting system network for a large facility where 6 diesel operated pumps (10.2Bar@568m3/hr)ea. and supplying diffrent areas through RTR pipes ( size varies from 36" to 10"). According to our supplier and...
Hello All,
I am designing a pump station ( 3 pumps, 2d/1s) pumping brackish water with a total flow of 70m3/hr through a DN160 Ductile iron pipe buried 1.5 m from FGL. The total length of the pipe is 2700m discharging into a Box Culvert. To reduce the water hammer effect I have installed a...
Hi all, as part of the design of a catalytic combustor, I had completed a PDE system that governs the temperature distribution of air and ceramic as hot air flows through a honeycomb Ceramic cylinder. I am positive that the PDE system is right, however when plotting the result using MathCad...
Hi all, it could be a simple question for some, why blowers are specified by static pressure not total pressure or dynamic pressure? I am new in this area!
Thanks!
Hi guys, I am trying hard to solve a First-Order System of 2 Partial differential Equations using MathCAD14.
I have 2 function: M(x,y) and N(x,y); 2 partial DE's:
Mx = M - N and Ny= N - M; and Boundary conditions: M(x,0)=a, N(0,y)=b, and M(0,x)=d; Could anyone help me solving this system?
Thanks
Hello everyone, I have to do some calculations on an existing honeycomb cylinder-shape made of ceramic material. Dia= 500mm and Length: 600mm. The cylinder will be connected to a gas turbine combustor outlet by a S.S pipe with air temperature reaching 1000deg and mass flow 4.1 kg/s. I need help...
Hi Guys, I am currently trying to calculate Wm1 using the effective gasket area on a Slip-on flange raised face. According to AS1210, Wm1= H + Hp with Hp= 2*b*(pi)*G*m*P.
I got different answer Hp= b*(pi)*G*m*P and dunno why here's what I have done:
Hp= P*m*A where A is the total area of gasket...
Hi, I am trying to design a customized flange for full face gasket( flat plate ). I have determined the number and size of the bolts required and now I am looking at calculating the stresses. Could anyone guide me on any book or website showing how to calculate the stresses?
Thanks you
Hi, I am trying to design a bolted flange based on Australian standards. Can COMPRESS do the bolt spacing calculation on a flange based on AS?
Thank You
