For the steam power plant described in Problem 9.13, assume the isentropic efficiencies of the turbine and pump are 85% and 80%, respectively. Find the components' specific work and heat transfers and the cycle efficiency.
Problem 9.13
A steam power plant, as shown in Fig. 9.3 operating in a Rankine cycle, has saturated vapor at 3.0 MPa leaving the boiler. The turbine exhausts to the condenser operating at 10 kPa. Find the specific work and heat transfer in each of the ideal components and the cycle efficiency.
Design a series of closely spaced parallel box beams that will support an asphalt road surface over a 10 foot wide, 40 foot long span. The hollow box beams are made of concurred and imbedded No. 8 steel rods (1 inch dia.).
Air enters a steady-flow turbine at 1600 K and exhausts to the atmosphere at 1000 K. The second-law efficiency is 85%. What is the turbine inlet pressure?
A nylon thread is to be subjected to a 10-N tension. Knowing that E=3.2 GPa, that the maximum allowable normal stress is 40 MPA, and that the length of the thread must not increase by more than 1%
A person who retires at age 62 can receive Social Security benefits of $1537 per month, but by waiting for the full retirement age of 66, the person will receive $2057 per month.
Three loads P1 = 2.4 kN, P2 = 4.4 kN, and P3 = 6.4 kN are suspended as shown from the cable ABCDE. Knowing that the maximum tension in the cable is 26 kN, determine the distance dC.
The beam is rigidly attached to a fixed wall at end B. with end D being supported by a rod of length L, Young's modulus E and crosssectional area A. A line load and a couple act on the beam. as shown. Using Castigliano's method. determine the load..
A projectile is fired with an initial velocity of 800 ft/s at a target B located 2000 feet above the gun A and at a horizontal distance of 12,000 feet. Neglecting air resistance, determine the value of the angle at which the projectile is fired.
For the beam and loading shown, write the equation of he shear and bending-moment curves and determine the magnitude and location of the maximum bending moment
A coal fired power plant can be modeled as a heat engine. If the power output of the plant is 200 MW and the thermal efficiency is 42%, determine the amount of coal used per day if the heat of combustion from the coal is 24,000 kJ/kg.
A perfectly mixed aeration pond with no recycle serves as the biological reactor for a small community. The pond receives 30m^3/d of influent with a BOD5 of 350mg/L that must be reduced to 20mg/L before discharge.
The water temperature is 14 C and the mean pore diameter is 0.33 mm. Is it permissible to use Darcy’s law under these circumstances? What is the reason for your answer?
