Thanks for the prompt response. From what i understand, steam power plants uses a Rankine cycle. Having said that, one of the practical ways to increase efficiency is to superheat the steam. Steam that are left in the boiler is further heated up to superheated state, which carries more energy...

This is not homework question, I'm just curious. Question: What is the purpose of a condenser in a steam power plant? I read that a condenser increases efficiency, but how? Since steam from the turbine exit ideally reduce only in temperature (but maintain the same entropy) why is there a...

hi, thanks for your response. i have a few further questions. a)for impulse of water, isn't it 1/3(kg/s) * 40(m/s) ? since it is rate of change in momentum, isn't it momentum/time? b)why is the impulse on the roof 0? how does it relate to the impulse equation? c) your impulse equation =...

i am not sure about that...as that is all the information given. but I'm assuming its with the horizontal as that's the way it is shown on in the diagram.

Homework Statement A fire hose sends 20 kg of water per minute against a burning building. The water strikes the building at 40.0 m/s and is deflected 60deg as shown in the figure. (a) What is the rate of change of momentum of the water? (b) What force does the building exert on the water? (c)...
