An airplane flies horizontally at 55.0 m/s. Its propeller delivers 1500 N of thrust (forward force) to overcome aerodynamic drag (backward force). Using dimensional reasoning and unity converstion ratios, calculate the useful power delivered by the propeller in units of kW and horsepower.
when the discharge upstream is suddenly increased to 70 cfs/ft. What is the speed and height of the surge wave
A 782 pound 4WD vehicle is designed to clime a 16 degree ramp. What is the minimum acceptable coefficient of friction between its tires and the ramp surface?
Sketch and annotate the drive train described above. What's the overall system gear ratio? Formula, Substitute/Solve,
A cylindrical bar of aluminum 19 mm (0.75 in) in diameter is to be deformed elastically by application of a force along the bar axis. Using E=10 psi (Modulus of Elasticity), determine the force that will produce an elastic reduction of 1e-4 in. in..
Steam enters the turbine of a simple vapor power plant with a pressure of 160 bar and a temp of 560 C and expands adiabatically to 0.08 bar
how long will it take the puck to slow down to a speed of 1m/s and how long will it take for the puck to stop completely? How far will the puck travel before it slows to 1m/s? You can assume the table is very very long.
A heat pump uses refrigerant-134a as the working fluid in an ideal vapour-compression refrigeration cycle between 0.14 and 0.8 MPa. The refrigerant leaves the compressor at a temperature of 40° C. Determine the pressure, temperature and enthalpy a..
determine the smallest allowable value of the coefficient of static friction between the collar and the rod if the collar is not to slide when a) a =15° b)a = 45°. Indicate for each case the direction of the impending motion.
Knowing that in the position shown the rod has angular velocity of 4 rad/s clockwise; determine the angular velocity of the rod after it has rotated through a 90°.
Calculations that show the material composition (fibre and matrix type and volume fractions) will meet the property specifications, and a justification of why this material composition is the cheapest option
Write a complete program consisting of a Main Program and Subprogram (you choose which type, but there should be only one) that fulfills the following requirements.
