Answer:
See explaination
Explanation:
Let's define tuple as an immutable list of Python objects which means it can not be changed in any way once it has been created.
Take a look at the attached file for a further detailed and step by step solution of the given problem.
Answer:
a. 318.2k
b. 45.2kj
Explanation:
Heat transfer rate to an object is equal to the thermal conductivity of the material the object is made from, multiplied by the surface area in contact, multiplied by the difference in temperature between the two objects, divided by the thickness of the material.

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
![h1 + \frac{v1}{2} + q = h2 + \frac{v2}{2} + w](https://tex.z-dn.net/?f=h1%20%2B%20%5Cfrac%7Bv1%7D%7B2%7D%20%20%2B%20q%20%3D%20h2%20%2B%20%5Cfrac%7Bv2%7D%7B2%7D%20%20%2B%20w)
put here value with
turbine is insulated so q = 0
so here
![3015.4 *1000 + \frac{10^2}{2} = 2431.7 * 1000 + \frac{90^2}{2} + w](https://tex.z-dn.net/?f=3015.4%20%2A1000%20%2B%20%5Cfrac%7B10%5E2%7D%7B2%7D%20%20%3D%20%202431.7%20%2A%201000%20%2B%20%5Cfrac%7B90%5E2%7D%7B2%7D%20%20%2B%20w)
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
