1. A turbine receives steam at 3000 kPa, 500?C and has two exit flows, one at 1000 kPa, 350?C with 20% of the flow and the remainder at 200 kPa, 200?C. Find the isentropic and second-law efficiencies.
2. Steam enters a turbine at 25 MPa, 550?C and exits at 5 MPa, 325?C at a flow rate of 70 kg/s. Determine the total power output of the turbine, its isentropic efficiency, and its second-law efficiency.
It is U) be mounted on a solid steel shaft with a heavy force fit. Specify the dimensions for the shaft and sleeve, and compute the stress in the sleeve after installation. Use the basic hole system.
What is the difference between R and Ru
Determine the moment of this force about the bolt center O
What are the basic assumptions of the 'traffic flow model' and 'capacity model' used in signal timing design. Discuss.
A cylindrical core, completely saturated with oil up to immobile water saturation, is immersed in water and the measured volume of oil displaced by imbibition of water
The phone lines to an airline reservation system are occupied 40% of the time. assume that the events that the lines are occupied on successive calls are independent. assume that 20 calls are placed to the airline.
We have a situation where hydrogen gas at 300 degrees C is flowing out of a tube at the rate of 100 mL/min. The tube is located in a fume hood operating at 25 degrees C and 1 atm.
Given the binary variables x1,x2,x3,x4 and x5, formulate a set of constraints that will enforce x3,x4, and x5 to equal one if x1=1 and x2=0.
Design and detail a brick veneer cladding for a multistory building that you are designing. Rather than trying to conceal the ashings and soft joints, work out a way of expressing them boldly as part of the architecture of the building.
Determine the relationship which governs the velocities of the two cylinders A and B. Express all velocities as positive down. How many degrees of freedom are present?
Are there any situations when parallel flow option may be preferred instead of a counter flow heat exchanger
Curves can be established by occupying cL or offset stations and then turning off appropriate deflection angles, or curves can be established by occupying a central control station and then turning off angles and measuring out distances-as determi..
