An R-134a refrigeration system is operating with an evaporator pressure of 200 kPa. The refrigerant is 10% in vapor phase at the inlet of the evaporator. The enthalpy and temperature of the refrigerant at the exit of the compressor are 360 kJ/kg and 70 /C respectively. If this system (with the refrigerant flowing at 0.005 kg/s) is used to cool a 750 kg product (initial temperature = 80 /C and specific heat = 3,000 J/kg-K), what will be the temperature of the product after 6 hours?

A convergingdiverging nozzle is designed to produce a Mach number of 2.5 with air. (a) What operating pressure ratio (prec/pt inlet) will cause this nozzle to operate at the first, second, and third critical points? (b) If the inlet stagnation pressure is 150 psia, what receiver pressures represent operation at these critical points? (c) Suppose that the receiver pressure were fixed at 15 psia. What inlet pressures are necessary to cause operation at the critical points?

A six-lane divided multilane highway (three lanes in each direction) has a measured free-flow speed of 50 mi/h. It is on mountainous terrain with a traffic stream consisting of 7% large trucks and buses and 3% recreational vehicles. The driver population adjustment in 0.92. One direction of the highway currently operates at maximum LOS C conditions and it is known that the highway has PHF=0.90. How many vehicles can be added to this highway before capacity is reached, assuming the proportion of vehicle types remain the same but the peak-hour factor increases to 0.95? Process: (1) determine passenger car equivalent for trucks and buses; (2) determine passenger car equivalent for recreational vehicles; (3) calculate heavy vehicle factor; (4) determine 15-min passenger equivalent flow rate for current conditions; (5) determine 15-min passenger equivalent flow rate at full capacity; (6) calculate the volume for current and capacity conditions; (7) take the difference of the two volumes to determine how many vehicles were added

1. Deformation of a Cylindrical Pressure Vessel A thinwalled cylindrical pressure vessel of inner radius r and thickness t r is subjected to an internal pressure p. The pressure vessel is made from steel which has elastic material constants E = 200 GPa and = 0.30. If the vessel has a length ` = 3 m, an inner radius of r = 0.65 m, and a wall thickness t = 15 mm, determine the following items for a pressure p = 25 MPa. Assume that elongation is positive and contraction is negative. (a) Determine the hoop (circumferential) strain in the pressure vessel. (b) Determine the axial (longitudinal) strain in the pressure vessel. (c) Determine change in the circumference of the pressure vessel caused by the internal pressure. (d) Determine the change in the outer diameter of the pressure vessel caused by the internal pressure. (e) Determine the change in the length of the pressure vessel caused by the internal pressure.

As discussed in the text, one possible performance enhancement is to do a shift and add instead of an actual multiplication. Since 9 x 6, for example, can be written (2 x 2 x 2 + 1) x 6, we can calculate 9 x 6 by shift ing 6 to the left 3 times and then adding 6 to that result. Show the best way to calculate 0 x33 x 0 x 55 using shift s and adds/subtracts. Assume both inputs are 8-bit unsigned integers.

A machine operates using air flow under steady conditions with the following inlet and exit flow parameters. At the inlet, the pressure is 1.75 MPa at a temperature of 300 K. The inlet velocity is 25 m/s. The inlet diameter is 20 cm. At the outlet, the pressure is decreased to 55 kPa at a temperature of 500 K. The outlet velocity is 100 m/s. The elevation increase between the inlet and outlet is 100 m. The machine includes a turbine operating at 5 kWDetermine mass flow rate through the machine.

Consider two cycles: one is the ideal Carnot cycle and the other is the ideal Rankine cycle. Both cycles are saturated liquids at the inlet to the pump and saturated vapor at the inlet to the turbine. If the maximum temperature for the Carnot cycle is equal to the maximum temperature for the Rankine cycle, answer (and give a brief explanation) if the quantities below for the Rankine cycle are greater than, less than, or equal to those for the Carnot cycle. EXPLAIN each answer.

Your engineering firm has been hired as a consultant to evaluate engineered channels to replace an existing natural stream. The existing channel has a length of 1.2 miles with an average bedslope of0.0042ft/ft. Thedesign flowfor this channel is2,250 cfs.The client requests that you conduct a feasibility study to replace the natural stream with a concrete-linedchannel. Base your design on the best hydraulic section and select two of the following section shapes to evaluate:rectangular, trapezoidal, triangular, and half-circularsections.Provide a freeboard of at least 10% of the flow depthat design discharge. Subcritical flowis preferredin the engineered channel. After completing the design of the channel, perform an extreme event analysis by determining the normal depth for a flow of twice the design flow. Discuss ifflooding is an issue for this extreme event.
