I have a natural gas pipe line, operating pressure 25 bar-a, operating temperature 60°C, fluid natural gas with density 0.8 kg/Nm3. On this line I have a vent line to the atmosphere with a ball valve DN 32. Let's suppose this DN 32 valve remains open; in this situation the main pipe line is...

where can I find, on Internet, a good - easy to read and print . and freeware edition of the psychrometric chart in the SI? Thanks everybody!

I have to define the performances of a gas turbine fed by natural gas for a new plant. I need then to define the tolerances of the guaranteed values (electrical power and gas consumption) and of the instruments to use to measure these values. Could you indicate me, please, which is the norm that...

I know the composition (in weight and in volume) of the exhaust gas from a gas turbine. How can I calculate is dew point? Thanks

I have to define the BOP for a plant in which there is a fire tube boiler for 12 t/h of saturated steam at 10 bar-g. I have decided, for economical reasons, don't to put in the plant a deaerator: in fact italian norms suggest, for these boilers, (fire tube boilers, FBT), a qualit of the water...

I have to study a reducing and cooling station for a steam turbine by-pass system. The reducing plant is controlled in pressure and temperature; it uses water, which injected at a certain temperature via spray nozzles with fixed area, to reduce the temperature of steam. I want to understand the...

I'd like to know the formula that permit to correlate the value of heat transfer coefficient in case of an heat exchanger with and without fouling, with the value of the fouling factor.

I have to calculate stresses and deflections in a continuous beam on two span of different lenght, in 2 situations: 1) 3 hinges with 2 concentrated loads in two diffferent points of one span 2) 2 hinges and one fixed joint with 2 concentrated loads in two diffferent points in one span I have...
