A solid titanium alloy [G 114 GPa] shaft that is 720 mm long will be subjected to a pure torque of T 155 N m. Determine the minimum diameter required if the shear stress must not exceed 150 MPa and the angle of twist must not exceed 7 degree. Report both the maximum shear stress and the angle of twist at this minimum diameter.

An insulated steady-flow mixing chamber has two inlets and 1 outlet. At inlet 1, the mass flow rate is 0.08 kg/s. At inlet 2, the mass flow rate is 0.15 kg/s. The average velocity at the outlet is 12.84 m/s. The area of the outlet is 0.01 m2. What is the specific volume of the outlet fluid (m3/kg) (3 significant figures) ?

10.1. Agency theory has been criticized for assuming that managers, left on their own, will behave in ways that reduce the wealth of outside equity holders when, in fact, most managers are highly responsible stewards of the assets they control. This alternative view of managers has been called stewardship theory. Would you agree with this criticism of agency theory?

Superheated steam at 40 bar absolute and 500°C flows at a rate of 250 kg/min to an adiabatic turbine, where it expands to 5 bar. The turbine develops 1500 kW. From the turbine the steam flows to a heater, where it is reheated isobarically to its initial temperature. Neglect kinetic energy changes. Write an energy balance on the turbine and use it to determine the outlet stream temperature. Write an energy balance on the heater and use it to determine the required input (kW) to the steam. Verify that an overall energy balance on the two-unit process is satisfied. Suppose the turbine inlet and outlet pipes both have diameters of 0.5 meter. Show that it is reasonable to neglect the change in kinetic energy for this unit.

Match the descriptions to the respective stage of team

development

forming stage

storming stage

norming stage

performing stage

The team transitions into this stage after completion of its first successful project.

In this stage, the team members come together for the first time.

In this stage, the members have a better idea of what the team expects of them.

In this stage, comfort and trust between the members is high.
