Question 2 Which of the following is correct about VB.NET? OVB.NET has complete support for object-oriented concepts. Everything in VB.NET is an object, including all of the primitive types (Short, Integer, Long, String, Boolean, etc.) and user-defined types, events, and even assemblies. All objects inherits from the base class Object. All of the above. 2 pts

Assume that you have a steady state heat exchanger. Subcooled liquid water enters (1) at 15 °C and exits (2) also subcooled at 25 °C with negligible change in pressure. R-134a enters (3) at 1.4 MPa, 90 °C, with a mass flow rate of 8 kg/min and exits (4) as a saturated liquid at 48 °C. The two flows do not mix. The heat exchanger is insulated, so heat transfer from the outer surface of the heat exchanger can be ignored. You can neglect changes in kinetic energy and changes in potential energy. Find: a) the mass flow rate of the liquid water stream, in kg/min, b) the rate of entropy change of the water (W/K), c) the rate of entropy change of the R-134a (W/K), d) the rate of entropy change of the heat exchanger as a system (W/K)
