Steam turbine Definition and 58 Threads

Hello, For sometime now I've been into electronics and i have forgotten most of my meager knowledge in thermodynamics. . Could you explain how a convergent-divergent nozzle works ? Steam at high temperature and high pressure but relatively low speed enters into the nozzle. Then why...

I have my solar power planned out...1200 2 inch mirrors on plywood that will be aimed at the sun and will have a focal pint about 4 feet from the board. i know how to make the steam system but i haven't a clue how to make a working turbine to create electricity. (steam will be the way of...

Any such thing as "small steam turbine"? I've a C-Band satellite dish. I'm going to attach 2" mirrors to the entire reflecting surface and aim it at the sun. Where the feedhorn was, I'm going to design some type of coil to pump water through which the focused sunlight will boil the water...

Hi, I was told that there was an inherent torque advantage to using a piston design over a turbine design (in this case for steam). I said I doubted there was any theoretical reason why this would be true, it would all depend on the design of the engine. My argument was that most turbines in...

Steam enters a turbine at 3 mpa and 450 c, expands in a reversible adaibatic process, (KE and PE are negligible) and exhausts at 10 kpa. The power output of the turbine is 800 kW. What is the mass flow rate? I did the problem but I don't know if the anwser is correct and wanted to check...

Hi All, I am a solar thermal enthusiast seeking to try out a few things. I need some info on using car aircondition compressor as a pico steam turbine if it is possible. Links, suggestions and opinions are welcome. Regards, Solomon.

I will start my junior year as a ME major in the fall, I currently am working for a power company on a co-op. I work with the Predictive Maintance department corporate so I am not at the plant all the time but have a question about the turbine that might be more of a generator question. If...

A steam turbine has an inlet of 2kg/s water at 1000kPa and 350C and velocity of 15m/s. The exit is at 100kPa, 100% quality and very low velocity. Find specific work and power produced. I have done a lot of these problems but it usually says adiabatic or the inlet and exit temp is the same...
