A steam power plant has a high pressure of 3 MPa, and it maintains 60?C in the condenser. A condensing turbine is used, but the quality should not be lower than 90% at any state in the turbine. For a turbine power output of 8 MW, find the work and heat transfer in all components and the cycle efficiency.
A stack (T=550*F and P=750mm Hg) was sampled using EPA Method 5. The total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T=60*F and P=800mm Hg). The mass of particles collected was 1.50g. Also, 72.0g of H2O was collected..
How many pounds of sulphur would be emitted from coal-fired power plants in the united states in 3 years. (each year. U.S electricity production in about 0.28 x 1012 watts, and coal has an energy content of about 30 x 106 J/kg
Design a cord (design the constants k and ) so the cord stretches 2.5 times the unstretched length, and the acceleration of the jumper doesn't exceed 3g, and the cord has zero stiffness at the bottom of a 400ft drop.
calculate the magnitude of the force on the piston pin A for the crank angle θ = 90° (Suggestion: Use the alternative moment relation, Eq. 6/3, with B as the moment center.)
Describe the reasons for enhancing drainage and situation where it is required. Explain some of the detrimental effects of drainage. Describe the types of drainage system indicating suitability criteria. 200- 250 word limit
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
It leaves the pump through a 4-in-diamter pipe at 15 psi. Assuming that the suction and discharge sides of the pump are at the same elevation, find the horsepower delivered to the water by the pump.
A Horizontal curve on a single-lane highway has its PC at station 123+70 and its PI at station 130+90. The curve has a super-elevation of 0.06 ft/ft and is designed for 70 mph. What is the station of the PT
All the members of the symmetrical rigid frame shown in Figure S11.2 are of uniform section. Determine the value of W at which elastic instability of the frame occurs in its own plane.
What are the quantitative measures of reliability (discuss measures for hardware, software, personnel, facilities, and data)?
What determines the minimum value of the duration of the output pulse
Determine the vertical deflection and the slope at the end of A of the bracket. Assume that the bracket is fixed supported at its base, and neglect the axial deformation of segment AB. EI is constant.
