1. Estimate the wind force on your hand when you hold it out of your car window while driving 55 mph. Repeat your calculations if you were to hold your hand out of the window of an airplane flying 550 mph.
2. Estimate the energy that a runner expends to overcome aerodynamic drag while running a complete marathon race. This expenditure of energy is equivalent to climbing a hill of what height? List all assumptions and show all calculations.
Given the enthalpy of formation for food waste to be -394.7 MJ/kmol, use the combustion reaction from Equation 4.11 to calculate its HHV (assume that the molecular formula is the same as switchgrass). Repeat this calculation for redwood (assume an..
One-half kilogram of water executes a Carnot power cycle. During the isothermal expansion, the water is heated until it is a saturated vapor from an initial state where the pressure is 1.5 MPa and the quality is 25%.
an ideal brayton cycle has reheat between the first and second staged turbines and regeneration following the second
Calculate Reynolds number for the process and hence the head loss due to friction. State any assumptions made and calculate the minor head losses for the system using both the equivalent length method and the number of velocity heads method.
A refrigerator uses a R-134a as the working fluid and operates on an ideal vapor-compression refrigeration cycle between 0.12 and 0.7 MPa. The mass flow rate of the refrigerant is 0.05 kg/s.
If the mass is driven harmonically by a 90-N force at 25 Hz, determine the equivalent viscous-damping coefficient if the coefficient of friction is 0.1.
you are manufacturing a frame for a vehicle out of some aluminum alloy 6061-t451 tubing. the frame is to be welded
A piston-cylinder device with a set of stops initially contains 0.6kg of steam at 0.8MPa and 500°C. The location of the stops corresponds to 60percent of the initial volume. Now the steam is cooled. Determine the compression work of the final state ..
The gas is expanded adiabatically ( dQ = 0) and quasi-statically until its temperature falls to - 50°C. What are its imtial and final pressures and its final volume?
cars a and b are traveling at va 72 mph and vb 67 mph respectively when the driver of car b applies the brakes abruptly
If peak-to-peak oscillations of the servo load (plant) under steady-state conditions have to be limited to no more than two degrees, what is the worst tolerable resolution of the resolver? Note that, in practice, the feedback sensor should have a ..
a new building to be located in a cold climate is being designed with a basement that has an l200 mm thick wall. inner
