a newtonian fluid fills the gap between a shaft and a concentric sleeve. When a force oƒ 788N is applied to the sleeve parallel to the shaft, the sleeve attains a speed oƒ 2m/s. if a 1400N force is applied, what speed will the sleeve attain? The temperature oƒ the sleeve remains constant.
Design a flat roof meeting certain mechanical performance criteria. The basic structure of the roof is a series of rectangular-section 'joists', made from softwood, that span the space to be covered by the roof.
engine B is supercharged with after cooling and has cylinder inlet condition of 80c and 130 k pa to avoid knock problem it is desirable to have the air-fuel temperature at the start of combustion in engine B to be the same as in engine A calculate..
Finding exit velocity from air nozzle, Air enters a nozzle operating at steady state at 800 ºR with a negligible velocity and exits the nozzle at 570 ºR.
Acceleration was uniform. If it assumed that the acceleration was uniform where the magnitute of the volocity of an airplane was changed from 120mph to 360mph in 6 seconds.
Find the Temperature of the Refrigerant, A closed vessel with a volume of 2 ft^3 contains 5 lb of Refrigerant 134a. A pressure sensor in the tank wall reads 71.39 lbf/in.^2 (gage).
Sketch and annotate the drive train described above. What's the overall system gear ratio? Formula, Substitute/Solve,
Saturated water vapor at 200oC is isothermally condensed to a saturated liquid in a piston-cylinder device. Calculate the heat transfer and the work done during this process in kJ/kg.
Calculate the number of vacancies per cubic meter in gold at 900°C. The energy for vacancy formation is 0.98 eV/atom. Furthermore, the density and atomic weight for Au are 18.63 g/cm3 (at 900°C) and 196.9 g/mol, respectively.
Determine the maximum horizontal displacement s of the block. Each of the two springs has a stiffness of k = 2500N/m and an unstretched length of 0.15 m.
The heating is to be done in a mixing tank by direct injection of the steam, all of which condenses. Determine the two inlet mass flows needed to meet the desired hot water flow rate.
Water is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 18 MPa. The condenser pressure is 6 kPa. How do I determine the quality of the fluid at the turbine exit
