At -12°C, refrigerant R-134a has vf = 0.0007498 m3/kg and vg = 0.1068 m3/kg. 3 kg of a saturated mixture of R-134a at -12oC has a quality of 0.93. Determine the specific volume and the total volume of the R-134a.
Given: vf = 0.0007498 m3/kg; vg = 0.1068 m3/kg; x = 0.93; m = 3.0 kg What will be an ideal response?

A function F is defined such that it equals 1 when a 4-bit input code is equivalent to any of the decimal numbers 3, 6, 9, 12, or 15. Function F is 0 for input codes 0, 2, 8, and 10. Other input values cannot occur. Use a Karnaugh map to determine a minimal expression for this function. Design and sketch a circuit to implement this function, using only AND and NOT gates.
