Question 1
I calculated the power production from a new type of steam turbine as
Power.
MC,
+1
where T, P, and v are the temperature, pressure and velocity of the steam going into the turbine,
Tour Pou and you are the temperature, pressure and velocity of the steam leaving the turbine, C, is
the heat capacity of the steam (units Joules/kg'C), it the mass flow rate of steam through the
turbine (units kg/sec), the steam density (kg/m³), the coefficient of dynamic friction in the
rotating shaft (not to be confused with viscosity which uses the same symbol), N the rotation rate of
the shaft (units 1/sec) and d the shaft diameter.
Using "engineering scrutiny," what "obvious" mistakes can you find with this formula? There are at
least 5, but list only the 3 of which you are most certain.
