A heavily insulated steam turbine operates steadily and is supplied with 1 kg/s steam at 2MPa, 400 deg C. If the outlet temperature is 100 deg C and the turbine has an output of 1000 kW determine the quality of the outlet steam, the rate of entropy generation and the isentropic efficiency of the turbine. (Changes in kinetic and potential energy are negligible).

Sketch the equilibrium band structure of pnp bipolar junction transistor (BJT). In point form, explain how
the application of a bias voltage at the “base” changes the band structure that you have drawn and can be
used to turn this device “on” and “off”. (a well-labeled equilibrium diagram will enable you to complete this without
any further band-structure diagrams)

1.What will be the impact on a company's profit if the sales mix shifts between low margin and high margin products? Explain different possible scenarios.

2.When does absorption costing net operating income and variable costing net operating income require reconciliation? Explain different situations with appropriate reasons behind such changes.

Which of the following best explains the acceleration mortgage clause?

The clause that allows the lender to charge points to the borrower.

The clause that allows lenders to call the entire balance due and payable immediately if the borrower defaults on the loan.

The clause that reverses the amortization of the loan.

The clause that changes the mortgage payments from once a month to once every two weeks.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26^oC with a volumetric flow rate of 0.18 m³/s. Refrigerant exits at 8 bar, 70^oC. Changes in kinetic and potential energy from inlet to exit can be ignored.

Determine the volumetric flow rate at the exit, in m³/s, and the compressor power, in kW.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -20^oC with a volumetric flow rate of 0.18 m³/s. Refrigerant exits at 9 bar, 70^oC. Changes in kinetic and potential energy from inlet to exit can be ignored.

Determine the volumetric flow rate at the exit, in m³/s, and the compressor power, in kW.

3. In the 24 months from January 2016 through December 2017, the variance of the monthly percent changes in the 1000 elements of an unweighted price index was 0.24. In 2018, the variance of the 12 months of data was 0.32. How do you ascertain whether the standard deviation has changed since 2017? Has it (assume a 95% level of confidence)?
