Is it possible to rotate turbine blades without any fluid means there is no requirement of water or air to rotate turbine blade.
Blades may rotates with the help of spring compression and expansion system and that spring will be mounted on blade surface.means if one blade moved then spring will pull another blade and it will be continue.
the 10 pounds weight is supported by the cord AC and roller and by a spring.if the spring has unstreched lenngth of 8 inches and the weight in equilibrium when d=a inches.determine the stiffness K of the spring?
Air at 250 kPA and 15C is being forced into a tire, which has a volume of 0.5m^3, at a velocity of 60 m/s through a 6 mm opening. Find the rate of change of the density in the tire.
A 10-kg mass slides down a ramp inclined at 30o from the horizontal a total vertical distance of 3 m. Determine the velocity of the mass when it reaches the bottom, neglecting friction and air resistance.
Calculate the force required in direct extrusion of 1100-O aluminum from a diameter of 6 in. to 2 in. Assume that the redundant work is 30% of the ideal work of deformation, and the friction work is 25% of the total work of deformation.
Niobium forms a substitutional solid solution with vanadium. Compute the weight percent of niobium that must be added to vanadium to yield an alloy that contains 1.55 x 1022 Nb atoms per cubic centimeter. The densities of pure Nb and V are 8.57 an..
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.
Sketch the frequency response of the system. Overlay the frequency spectrum of the excitation and as you start the system up, increasing Ω from 0 to 60 rpm, what speeds are most likely to excite large amplitude response? Why?
A satellite has been placed in a circular, sun-synchronous orbit at an altitude of 1300.0 km. The satellite has a mass of 5,000.0 kg. What is the K.E. of the satellite?
Draw the Mohr's circle for this stress state, deterrnine the principal stresses and the angle of the principal direction to the x-axis and determine the maximum shear stress.
Assuming the plant operates on the ideal vapor-compression cycle using refrigerant 134-a between the pressure limits of 120 and 700 kPa, determine
refrigerant -134a at 800kPa and 25 C is throttled to a temperature of -20C. determine the pressure and the internal energy of the refrigerant at the final state.
