The efficiency of a steam power plant can be increased by bleeding off some of the steam that would normally enter the turbine and usingit to preheat the water entering the boiler. in this process, liquid water at 50oc and 1000 kpa is mixed with superheated steam at 200oc and 1000 kpa. if the plant operators want to produce a saturated liquid at 1000 kpa, what ratio of mass flow rates of water and superheated steam are required? [20]

what is the question because that is not a question.

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

i had this question and the answer was 3.15 miles.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
