Determine the volume generated bounded by the curves y= 1/x, 2x - y =0, x=10, and the x-axis. Rotated about the x-axis. 

A steam turbine receives 362,500 kg/h of steam throttled at 8.7 MPa and 410OC. steam leaves the high pressure turbine shell at 2 MPa with 7.58 degrees of superheat. Reheated steam is at 1.9 MPa and 410OC. Condensate is at 78OC. For a generator output of 100 MW at 94% efficiency, calculate (a) the combined thermal efficiency, (b) the actual condition of exhaust steam, (c) the thermal efficiency of the ideal engine, (d) the combined engine efficiency, and (e) the ideal thermal efficiency of the cycle without pressure drop through reheater

The Stanton number is the equation that deals with the heat transferred into a fluid, compared to the thermal heat capacity of that fluid, true or false?

1. Two men carry a weight of 2 kN by means of two ropes fixed to the weight. One rope is inclined at 45° and the other at 30° with their vertices. Find the tension in each rope?

1. ABCD is rectangle, in which AB = CD = 100 mm and BC = DA = 80 mm. Forces of 100 N each act along AB and CD and forces of 50 N each at along BC and DA. Find the resultant moment of the two couples.?

A 100-mm radius cylinder filled with water is fitted with a piston of negligible weight. A force F is applied to the piston. The manometer attached is filled with mercury (SG = 13.57) and is displaced as shown. Determine the force F.
