A space experimental package of mass m is supported on an elastic suspension of stiffness k in the space shuttle. During launching, the space shuttle (base of the elastically supported package) experiences an acceleration of where α is a constant. Find the time variation of the displacement, x(t), and the relative displacement, x(t) - y(t), f the package. Assume zero initial conditions.
The mass flow rate through a steam turbine operating under steady conditions is 100 kg/s. Steam enters the turbine at 12 MPa and 400oC. A mixture of vapour and liquid water exits the turbine at 10 kPa. At the exit state 93% of the mass of the water i..
The airspeed of an aeroplane is measured with a Pitot tube. The plane is flying at an altitude of 10000m, and the Pitot tube measures a gauge pressure of p = 10kPa. What is the airspeed of the plane?
air enters the compressor of a regenerative gas-turbine engine at 300k and 100 kpa where it is compressed to 800 kpa

a hydraulic dredge is used to dredge sand from a river bottom. estimate the thrust necessary to keep the boat
A compressor receives 0.1 kg/s R-134a at 150 kPa, -10C and delivers it at 1000 kPa, 40C. The power input is measured to be 3 kW. The compressor has heat transfer to air at 100 kPa coming in at 20C and leaving at 30C (i.e. like a heat exchanger). What..
For the system shown below in the figure, calculate the vertical distance between the surfaces of the two reservoirs when water at 10° C flows from A to B at the rate of .03 m3/s. The elbows are standard. The total length of the 4-inch pipe is 100..

White noise has a constant level when measured in frequency bands of constant width. Suppose a noise generator produces white noise over the octave bands 0.5,1,2,4,8 khz. Find the overall un weighted and a-weighted sound pressures if a sound pressure..
A comparable living standard in Toronto and Mexico City was attained for about $64,000. Suppose an executive wants to determine whether there is any difference in the average annual cost of supporting her family of four in the manner to which they..
Water, SAE 30 motor oil, and honey flow through three 25 cm diameter pipes. Each pipe passes a volumetric flow rate of Q = 0,01 m3/s. Assume the densi- ties of these fluids are water = 1, 000 kg/m3, oil ; 850 kg/m3, and honey = 1,300 kg/m3, and the v..
