A steam turbine operates with 1.6 MPa and 350 degrees C steam at its inlet and saturated vapor at 30 degrees C at its exit. The mass flow rate of the steam is 16 kg/s, and the turbine produces 9000 kW of power. Determine the rate at which heat is lost through the casing of this turbine.
A map of a burned area obtined from remote sensing contains 120 pixels. The remote sensing image shows that the fire is isolated to 73 of 120 pixels.
Find the shear strain that results if a force of magnitude 8×10^5 is applied to the top square face of the plate, parallel to the side, and a force of equal magnitude is applied in the opposite direction to bottom face of the plate.
A rod of length 0.850 m is attached to a pivot at one end. A force F of 2.30 N is applied to the end of the bar opposite the pivot. The force makes an angle of 65.0o with the bar. (The ? in the figure is the angle for the "line of action" of the f..
