Astronaut Alan Shepard took a golf ball to the Moon. He hit what is thought to be the longest golf drive in history. What speed would an astronaut need to give a lunar golf ball in order to put the ball in orbit around the Moon? Do you think it co
The turbine is adiabatic, and kinetic and potential energy changes are negligible. If the isentropic turbine efficiency is 75%, determine the work per unit mass flow in KJ/kg, and plot on an h-s diagram.
Determine if this device is consuming or generating work? How much? Also determine the entropy change for the flowing air and comment on its value and sign.
To answer the question input only the actual number. Do not include units. Do not give your answer in sentence form -- just include the numerical answer rounded to exactly 4 decimal places.
If 0.330 mol of liquid CS2 and 26.9 g of gaseousO2 are reacted stoichiometrically according to the balanced equation, how many moles of gaseous SO2 are produced?
Assuming an ideal gas, find P_2 using both the ideal gas tables and assuming a constant specific heat ratio at the average temperature.
Find the heat transfer and work per unit mass of air in KJ/kg for each process of the two cycles, and compare the thermal efficiency of each. Assume constant specific heats at room temperature, and k=1.4.
