During the entry of the space shuttle into the earth’s atmosphere, maximum stagnation point heating occurs at the trajectory point corresponding to an altitude of 68.9 km, where ρ∞ = 1.075 × 10−4 kg/m3, and a flight velocity of 6.61 km/s. At this point on its entry trajectory, the shuttle is at a 40.2 degree angle of attack, which presents an effective nose radius at the stagnation point of 1.29 m. If the wall temperature is Tw = 1110 K, calculatethe stagnation point heating rate.

A converging nozzle with an exit diameter of 6 cm is attached to a reservoir maintained at 30 degrees C and 150 kPa absolute. Determine the mass flux of air flowing through the nozzle if the receiver exits to the atmosphere. Use applicable equations. Express in kg/s snd in 3 decimal places.
Saturated steam at 10 bar pressure is supplied to increase the temperature of the feed natural gas from its inlet temperature of 30°C to within 15°C of the steam outlet temperature. All steam properties can be verified in the steam table, attached. Evaluate the mass flow rate of the steam supplied, if about 20% of the steam is still uncondensed at the exit. The relevant properties of Natural gas (NG) are as follows: NG Flow Rate = 1500 kMol/hour Average specific heat Capacity of NG = 40 kl/kMol.°C.

Problem 3 – Sparky needs helium for an experimental project. The helium is stored in a storage tank at 20°C and 300 kPa. The helium exits through a converging nozzle to the environment (100 kPa atmospheric pressure) and has 10 mm exit diameter. Determine the exit flow rate of the helium. Helium’s ratio of specific heats is 1.667. This is a compressible flow problem. Only use equations and tables from the textbook to solve this problem. Note the figures in the textbook and textbook appendices are based in air, not helium, and are not valid for this problem.
