Average sea-level air pressure is approximately 1013.25 mbar (mbar stands for millibar). It has been found that the air pressure h meters above sea level is given (at least approximately) by the formula $$P(h) = 1013.25e^{-(0.000118576)h}$$ Approximate the instantaneous rate of change at h = 1000 meters by computing the average rate of change from 1000 to 1001. Interpret your answer in the context of air pressure.
Question 5 (10 marks). Prior to tossing a coin, it is believed that the chance of tossing a head is equally likely to be $\frac{1}{3}$ or $\frac{2}{3}$. The coin is tossed twice, and both tosses result in a head. Determine the posterior probability of tossing a head.

Problem 3 (40 pts) The total temperature and the static temperature of the flow downstream of a turbine are Ts=1000K and Ts=950K. Assuming cp = 1004 J/kg and γ = 1.4, calculate: a) The velocity of the flow downstream of the turbine V5. (10pts) b) The temperature T, knowing that pt9/p9 = 5. (10pts) The velocity of the flow downstream of an isentropic nozzle located just downstream of the turbine (10pts) The Mach number of the flow at the exit of the nozzle, knowing that R = 287 J/(kgK).

Questions 4) An engine operating on gasoline (i.e. an Otto cycle) has a compression ratio of 9. The intake is 1.5 bar and 315K. Assume a cold air standard. $MW_{air} = 29$, $\gamma = 1.4$. The engine has a clearance volume of 30 cc. a. What is the displacement of the engine? b. What is the temperature after the compression stroke but before the spark? c. What is the power developed in this engine if the specific amount of heat added is $q_H = 1800$ kJ/kg, and the engine operates as a 4-stroke at 2400 RPM?
