The mass flow rate into a steam turbine is 1.5 kg/s, and the heat transfer from the turbine is 8.5 kW. The following data are known for the steam entering (i) and leaving (e) the turbine:

P_i = 2.0 MPa
T_i = 350C
V_i = 50 m/s
z_i = 6 m

P_e = 0.1 MPa
x_e = 100%
V_e = 200 m/s
z_e = 3 m (above the reference elevation with g = 9.8066 m/s^2)

Determine the power output of the turbine.

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
