Consider an object of characteristic length 0.01 m and a situation for which the temperature difference is 30°C. Evaluating thermophysical properties at the prescribed conditions, determine the Rayleigh number for the following fluids: air (1 atm, 400 K), helium (1 atm, 400 K), glycerin (285 K), and water (310 K).
two kg of superheated steam contained in piston cylinder at 400 c and 600 kpa are cooled at a constant pressure by
consider a rankine cycle with water as the working fluid. superheated vapor enters the turbine at 480degc and 100 bar
the power output of an adiabatic steam turbine is 5.5 mw. at the inlet p 2.0 mpa and t 435 degc. the steam enters the
A steel bar of 100mm length tapers from 12mm×10mmfrom one end to 30mm×20mm at the other. If the stress in the bar is not to exceed 100mpa,find the magnitude of the axial force. Also find the change in its length. Take E as 200Gpa
The 10 kg wedge B shown in Figure 7.19 is held at rest on an incline of 30? by stop C when it is struck by the 50 g bullet A, which is traveling horizontally with speed vA = 900 m/s. Assume that the bullet is stopped instantaneously by the block.
Determine the value of the hysteresis-damping constant ß the equivalent viscous-damping constant and the energy loss per cycle for an amplitude of 10 mm.
If the tube surface temperature is Ts = 350 K and the gas-side convection coefficient is hg = 30 W/m2 · K, what is the rate of heat transfer to the water per meter of pipe length?
consider a stable nocturnal boudary layer in a 12 hr night. the wind is blowing at 5 ms and the surface is cooled with
A fishnet is made of 1-mm-diameter strings knotted into 2x 2 cm squares. Estimate the horsepower required to tow 300 ft2 of this netting at 3 kn in seawater at 20°C. The net plane is normal to the flow direction.
A flat bar is to be rolls but the rolls refuse to bite (the bar is not drawn into the roll gap). State at least two measures that could be taken.
Potential in a conducting box. A three-dimensional cubic box, with dimensions a x a X a is grounded on four sides. The two sides at z = a and at x = a are connected to a constant potential as shown in Figure 5.53. Calculate the potential everywher..
initially 0.05 kg of air is contained in a piston-cylinder device at 200 degc and 1.6 mpa. the air then expands at
