Homework Statement
In the turbine steam changes its specific enthalpy and velocity from (3450) kJ/kg and 85 m/s at the inlet to (2630) kJ/kg and 190 m/s at the outlet. (A) Determine the power generated per 1 kg of the steam if the process is adiabatic. (B) Determine also the power generated if the heat lost to surroundings is 10kJ per 1kg of steam flowing through the turbine. Neglect change in potential energy.

Hi there again. I have a second problem for which I don't have an answer to compare with, hence I'm kindly asking someone to check the solution of mine. lower case w and q are the work and heat per 1kg respectively, and w's with a vector are of course the velocities at the inlet and at the outlet.

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
