Question 6 1 pts At the start of the year, you opened an online E*Trade account and decided to invest $5,000 in the stock market. You followed the market closely and made trades every few days, buying and selling various stocks a total of 100 times throughout the year. Each time you transacted (i.e., 100 times), E*Trade charged you a $6 fee/commission. The S&P 500 finished up 21% this year, and your picks performed as well as the market--you were also up 21%, before transaction fees. What was your return this year after taking fees into account? Ignore capital gains taxes and assume for simplicity that all commissions were paid at the end of the year. 9% 13% 16% 20% 23% 27%

Problem 4 - Energy balance in a nozzle Steam at 0.6 MPa and 200 degC enters an insulated nozzle with a velocity of 50 m/s. It leaves at a pressure of 0.15 MPa and a velocity of 600 m/s. a. Create a schematic representation of the nozzle and draw the boundary of the system needed to answer the next questions. Include the mass and energy interactions across the boundary. b. Convert the fluid velocities at the entrance and exit in to units of mph. (show your conversions) c. Create a governing equation for this nozzle from the general energy balance equation and cross-out any terms that are likely to be irrelevant or have little contribution in the equation. d. If the final state of the steam is superheated, determine the final temperature of the steam. If the final state is saturated, determine its quality. e. List the assumptions and approximations that were needed to solve this problem. f. Identify (sketch) the two states of the working fluid (entrance and exit) on both a P-v diagram and a T-v diagram.
