At the beginning of compression process of an air standard dual cycle operating with a compression ratio of 15.88, the pressure is 95 kPa and the temperature is 300 K. The cutoff ratio for the cycle is 1.15. Determine the thermal efficiency of cycle, if the pressure increases by a factor of 2.15 during the constant volume heat addition process. Use table F2 for variation of specific heats with temperature in the analysis.

The seawater through which a boat sails moves 4 knots towards the East with respect to the bottom of the sea. The boat moves 15 knots with a direction of 60 degrees north of East with respect to the seawater.

a) What is the velocity, magnitude and direction, of the boat with respect to the bottom of the sea.

b) To navigate in a determined time interval and to a given destiny the boat requires a speed of 22 knots in a direction of 45 degrees west of North with respect to the bottom of the sea. What is it's velocity with respect to the water?

Consider a Rankine cycle with an ideal intermediate steam pickup, one of which is open and the other is closed feed water heaters. The steam enters the turbine at 12.5 MPa pressure and 550 degrees Celsius temperature and expands to 10 kPa condenser pressure. The steam separated from the turbine at 0.8 MPa pressure is sent to the closed feed water heater and the steam separated at 0.3 MPa pressure is sent to the open feed water heater. The feed water is heated to the condensing temperature of the steam leaving the turbine in the closed heater. The steam comes out of the closed heater as a saturated liquid, then the pressure is lowered into a valve and sent to the open feed water heater. Show the cycle in a T-s diagram with saturated liquid and saturated vapor curves.

a)

Water flow that must pass through the boiler for the production of 250 MW net power,

b)

Calculate the thermal efficiency of the cycle.

A spring with a spring rate of 75 lb/in has a working deflection of 1 in. It provides a minimum of 150 lb at installation. The spring is formed from 0.25 in diameter unpeened music wire. The coil has squared and ground ends, and it fits in a 2.1 in diameter hole with 0.1 in clearance.

Assuming a 15% clash allowance, find:

a) Safety factor for infinite life in fatigue

b) Shut height

c) Safety factor at shut height

d) Total number of coils

e) Free length

A single-tooth hardened-steel worm has a catalog rating of 2000 W at 600 rev/min when meshed with a 48-tooth cast-iron gear. The axial pitch of the worm is 25 mm, the normal pressure angle is 14.5°, the pitch diameter of the worm is 100 mm, and the face widths of the worm and gear are, respectively, 100 mm and 50 mm. Determine the three components of the load on the worm.
