Answer:

Hence it is proved that Stokes-Oseen formula is dimensionally homogenous.
Explanation:
For equation to be dimensionally homogeneous both side of the equation must have same dimensions.
For given Equation:
F= Force, μ= viscosity, D = Diameter, V = velocity, ρ= Density
Dimensions:



Constants= 1
Now According to equation:
![\frac{ML}{T^2}=[\frac{M}{LT}][L] [\frac{L}{T}] + [\frac{M}{L^3}][\frac{L^2}{T^2}][L^2]](https://tex.z-dn.net/?f=%5Cfrac%7BML%7D%7BT%5E2%7D%3D%5B%5Cfrac%7BM%7D%7BLT%7D%5D%5BL%5D%20%5B%5Cfrac%7BL%7D%7BT%7D%5D%20%2B%20%5B%5Cfrac%7BM%7D%7BL%5E3%7D%5D%5B%5Cfrac%7BL%5E2%7D%7BT%5E2%7D%5D%5BL%5E2%5D)
Simplifying above equation, we will get:

Ignore "2" as it is constant with no dimensions. Now:

Hence it is proved that Stokes-Oseen formula is dimensionally homogenous.
Answer:
power developed by the turbine = 6927.415 kW
Explanation:
given data
pressure = 4 MPa
specific enthalpy h1 = 3015.4 kJ/kg
velocity v1 = 10 m/s
pressure = 0.07 MPa
specific enthalpy h2 = 2431.7 kJ/kg
velocity v2 = 90 m/s
mass flow rate = 11.95 kg/s
solution
we apply here thermodynamic equation that
energy equation that is

put here value with
turbine is insulated so q = 0
so here

solve we get
w = 579700 J/kg = 579.7 kJ/kg
and
W = mass flow rate × w
W = 11.95 × 579.7
W = 6927.415 kW
power developed by the turbine = 6927.415 kW
