My Physics teacher keeps giving us way too much work to do at home.
Answer:
52.5°C
Explanation:
The final enthalpy is determined from energy balance where initial enthalpy and specific volume are obtained from A-12 for the given pressure and state
mh1 + W = mh2
h2 = h1 + W/m
h1 + Wα1/V1
242.9 kJ/kg + 2.35.0.11049kJ/ 0.35/60kg
=287.4 kJ/kg
From the final enthalpy and pressure the final temperature is obtained A-13 using interpolation
i.e T2 = T1 + T2 -T1/h2 -h1(h2 - h1)
= 50°C + 60 - 50/295.15 - 284.79
(287.4 - 284.79)°C
= 52.5°C
Answer:

Determine the percentage error
First, we calculate the mean

This gives:



Next, calculate the mean absolute error (E)

This gives:
![|E| = \sqrt{\frac{1}{6}*[(1.54 - 1.51)^2 +(1.53- 1.51)^2 +.... +(1.45- 1.51)^2]}](https://tex.z-dn.net/?f=%7CE%7C%20%3D%20%5Csqrt%7B%5Cfrac%7B1%7D%7B6%7D%2A%5B%281.54%20-%201.51%29%5E2%20%2B%281.53-%201.51%29%5E2%20%2B....%20%2B%281.45-%201.51%29%5E2%5D%7D)



Next, calculate the relative error (R)



Lastly, the percentage error is calculated as:
