An airplane moves forward at a speed W1= 971 kph. The frontal intake area of the jet engine is A1 = 0.8 m2 and the entering air density is ρ1 = 0.736 kg/m3. A stationary observer determines that relative to earth, the jet exhaust gases move away from the engine with a speed o V2 =1050 kph. The engine exhaust area is A2 = 0.558 m2, and the exhaust air density is ρ2 = 0.515 kg/m3. Estimate the mass flow rate of fuel into the engine in kg/h.
Solve this problem with a linear programming model. Describe the optimum mix of raw materials and production levels for the products. How much profit does the business make?
Treat the locomotive as a particle and assume that the railroad tracks are rectilinear and horizontal.
Determine the temperature of the electric heater element and drawing of the temperature profile.
An air heater may be fabricated by coiling Nichrome wire and passing air in cross flow over the wire. Consider a heater fabricated from wire of diameter D=1 mm, L= 2m, electrical resistivity rho=10^-6 ohms, thermal conductivity k=25W/mK, and emiss..
Also determine the axial force and deformation of the diameter due to temperature rise. Let E = 120 GPa and Co-efficient of linear thermal expansion = 0.0000168 per °C.

the suspended load exerts a force F=600 lb at A, and the weight of the bar OA is negligible. Determine the tensions at the cables and the reactions at the ball and socket support O
In order to increase production rate, a reactor setpoint was increased from 160 psig to 190 psig. The reactor pressure transmitter was recalibrated from 0- 200 psig to 0- 300 psig. What is the percent span for the old and new setpoints?
Plot the lift and drag forces exerted on an airfoil as a function of velocity. Use velocity values going from 0 to 45 m/s on a log-linear plot (log-scale on the y axis).
