Saturated water with a quality of 0.25 and a temperature of 300°F enters an uninsulated diffuser at a velocity of 510 ft/s. The mass flow rate is 5.2 lbm/s.
(a) If the water is to exit as saturated water vapor at a temperature of 300°F, with a velocity of 25 ft/s, determine the necessary heat transfer rate. (b) Using your model of a diffuser, determine the necessary heat transfer rates for the flow to exit as a saturated substance with qualities ranging from 0.40 to 1.0. (c) Using your model of a diffuser, determine the necessary heat transfer rates for the flow to exit as a saturated vapor at 300°F, with exit velocities ranging from 0 ft/s to 300 ft/s. Given: Water: x1 =0.25; T1 = 300°F; V1 = 510 ft/s; x2 = 1.0; T2 = 300oF; V2 = 25 ft/s;m?=5.2 lbm/s What will be an ideal response?

Answer the following statement(s) true (T) or false (F)
1. In a residential occupancy, all circuits are connected with two- or four-conductor cable. 2. The term double-throw means that the switch will make connection with a stationary contact when moved or thrown in either of two directions. 3. When making three-way switch connections using two, three, or four conductor cables, it is permissible to connect any of the conductors to the hot conductor. 4. Four-way switch connections are actually made with two- and three-conductor cable. 5. The National Electrical Code requires that neutral, or grounded, conductors be white or yellow.
