200Kg/min superheated steam at 40 bar and 350C enters a turbine through a 7.5cm ID pipe. It exits at 5bar as saturated steam through a 5cm ID pipe neglect the change in potential energy of the system. What is the temperature of the outlet saturated system? How much energy is transferred to or from the turbine?

Air undergoes an isothermal expansion as an ideal gas in a closed system.  The air pressure increases in the process. True or False?

A monatomic ideal gas is compressed isothermally from a volume of 2.0m^3 to 1.0 m^3. The initial pressure is 20 kPa. a. Find the work done on the gas from initial state to final state. b. Find the change in the internal energy of the gas. c. Find the amount of heat exchanged.

Saturated vapor water at 100 kPa enters an isentropic compressor and exits at 2 MPa. Note that isentropic implies adiabatic and reversible. a) What is the temperature of the outlet in \deg C. Round to one decimal place. b) How much work, in kJ/kg, must be used for this process? Round your answer to one decimal place. Hint: Don't use temperature to perform the interpolation!

Q1/ A volume of the vessel A is 0.5 m' contains saturated water at 275 °C, 80% quality. The pressure of cylinder B will be floated at 300 kPa, cylinder B in the beginning is empty. The air is flowed into cylinder B when the valve is opened and reaches to equilibrium state of 300 kPa, 275 °C. Determine the heat transfer during the process.

Problem 1/MatlabGrader (20 points) (Core Course Outcome 4) Develop a Matlab function myFitExam that finds the best fit of the function p(t) = as sin³ (t) + b sin² (t) + csin(t) + d (1) to a given set of data points (ti, pi) using regression. Here t is in radians. The function input shall be ⚫t: column vector of data values t ⚫ p: column vector of data values p The function output shall be • a: scalar containing the best fit coefficient a b: scalar containing the best fit coefficient b c: scalar containing the best fit coefficient c d: scalar containing the best fit coefficient d In the function use only functions developed in this class in modules 1 - 4. You do not need to provide these functions in your submission. They will be provided when assessing your function after the deadline. Note: no assessments will be performed on your submitted function before the exam deadline. Scores on Canvas for this problem before the exam has been fully graded are meaningless.
