A subsonic airplane is flying at a 3000-m altitude where the atmospheric conditions are 70.109 kPa and 268.65 K. A Pitot static probe measures the difference between the static and stagnation pressures to be 35 kPa. Calculate the speed of the airplane and the flight Mach number.
What is the recommended clear zone distance for the following roadway situations? (Use the Clear Zone nomograph to find solutions)
Water flows through a tube at a rate of 7.5 kg/min while heat is added to it at a rate of 4.5 kW. If water entered at 20 degrees celcius, determine the exit temperature. Assume the pressure remains constant at 1 atm throughout.
a. Determine the shear and moment diagram. b. Calculate the maximum normal stress on the top of the beam, on the bottom of the beam and indicate in terms of x its location.
Determine the maximum force (P) that can safely applied to a steel tee section (20 feet in length) with the point loads at 5 feet from each end. Fixed at one end, pin at the other.
For a 30ft simply supported beam, there is a uniform load of 1.5 k/ft. along the length and two point loads of 20 kips each spaced at (from x=0 to x=30ft left to right) x=10ft and x= 20 ft.
a floating platform is supported at each corner by a hollow sealed cylinder 1 m in diameter, the platform itself weighs 25kN in air and each cylinder weighs 1.2kN per meter of length.
An inventor claims that an engine produces 120 kw with a fuel consumption of 20 kg/h. The energy content of the fuel is 36,00 kJ/kg. The energy is received at a mean temperature of 500C and rejected at a mean temo of 50 C. Which laws of thermodynamic..
