when the temp rises the liquid volume should decrease because pressure increases and more steam is produced. This is making more since now! If I find the before and after specific volumes of the steam and water I can find how large the pressurizer needs to be so that it can handle a 1% pressure...

is there a free copy anywhere? I have "Powerplant Technology" book and already spent a fortune on that...

Yes...

i found the mass of steam and water in the pressurizer and multiplying them by their corresponding specific volumes I got a volume of 8000 ft^3 which is the volume of the primary loop, so obviously I did something wrong

how to you find the pressure rise in the pressurizer though?

I have a simple vapor power plant with a boiler, turbine, condenser and pump. I have the pressures leaving the boiler, entering the turbine, leaving the turbine and entering the condenser, leaving the condenser and entering the pump. I also have the temps for the above except I have the quality...

for k=2 i got 3.8 as the profit but for k=3 what do i change in my formula when referring to the pmf chart??

okay the profit for k=2 i got 3.8 when i am calculating it for when k=3 is this equation correct? -1(3)+2(.1*1+.2*3.8+.4*3.8+.3*3.8) i may be going off a longshot but i used the profit from k=2 for the values of x in this equation. I just want to make sure I am doing k=3 right so i can figure...

i don't think its open ended, because R_k= -1k+2*Y_k since R_k is the profit could i simply find the expected value is 1, 2, or 3 are sold that's it?

what?

I posted this in the wrong section before and meant to put it here, so i apologize if you seen this before. X=demand for the magazine with pmf x | 1 2 3 4 p(x)| .1 .2 .4 .3 Shop owner pays $1.00 for each copy of mag. and charges $2.00. If mags. left at end of week are not worth...

ive been work on this for a while and for the probability that component 2 works given the system works I got 0.76. and for the probability that component 3 works given the system works I got 0.604... anyone want to check that because i followed my notes from my teacher and applied them the way...
