**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:

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
