Steam enters the turbine of a single vapor power plant with a pressure of 10 MPa and a temperature of 580 C and expands adiabatically to 6 kPa. The isentropic turbine efficiency is 85%. Saturated liquid exits the condenser at 6 kPa and the isentropic pump efficiency is 82%.
A) What is the quality of the steam leaving the turbine
B) What is the turbine work output per kilogram of steam circulated
air flows through a horizontal iron tube (e=0.15m) at Q=5.7x10-2 m3/s. find the pipe diameter if the pressure drop is 3.5kPa per 30.5m of pipe. air density = 1.23kh/m3 dynamic vicosity = 1.79 x 10-5 N.s/m2)
Items are inspected for flaws by two quality inspectors. If a flaw is present, it will be detected by the first inspector with probability 0.9, and by the second inspector with probability 0.7. Assume the inspectors function independently.
a rectangular clarifier with a lengthwidth ratio of 31 receives a flow of 850m3day. the clarifiers depth is 4.0m and
A rear-wheel-drive car 2600 lb, has an 80-inch wheelbase, a center of gravity 20 inches above the road surface and 30 inches behind the front axle, a drivetrain efficiency of 85%, 14-inch-radius wheels,
What should be the length of an aluminum wire of 6 mm in diameter so it can be twisted one full turn without exceeding a shear stress of 42 MPa G = 27 GPa.
Why is it necessary to require such conditions-sand cement ratio, w/c ratio and type of sand. A graded sand is specified for use in the mortar cube test. What would be the likely results if a one-sized sand was used instead of a graded sand.
It is expected that 95% saturation will be attained. Calculate the volume of soil that will be needed if the void ratio of the fill material is 1.3
An area that varies in elevation from 463ft - 634ft is being mapped. What contour intervals will be drawn if a 50ft interval is used. Which lines are emphasized.
A conical tube of length 8 m fixed vertically with its smaller end upwards. The velocity head and pressure head at upper ends are 1.27 m and 2.50 m respectively.
Determine the volume flow rate per unit width amd tje shear stress of the upper plate (Start with the full, three-dimensional Navier-Stokes equations and the continuity equation, simplify them, and then solve them
Write a program that will ask for the part number for two different parts (i.e. PX_12345, and ABC_329). Display these parts in ONE message box, in numerical order (i.e. the segment of the part number to the right of the underscore character).
