1. Water at 800?C, 15 MPa is flowing through a heat exchanger giving off energy to come out as saturated liquid water at 15 MPa in a steady-flow process. Find the specific heat transfer and the specific flow exergy the water has delivered.
2. A rock bed consists of 6000 kg granite and is at 70?C. A small house with a lumped mass of 12 000 kg wood and 1000 kg iron is at 15?C. They are now brought to a uniform final temperature with no external heat transfer by connecting the house and the rock bed through some heat engines. If the process is reversible, find the final temperature and the work done in the process.
A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe,
determine the velocity and acceleration of point C of the belt, (a) immediately before the power is turned off. (b) 9 s later.
A slope face is cut in granite with sheet joints dipping as shown. A) Disregarding information about cohesion or friction along the joint surfaces, state why the cut is stable
Consider the simply supported beam that has one external load applied to it. At a cross- section that cuts through the carriage bolt, there are 5 points at which the states of stress must be identified.
a gate shaped like .25 of a cylinder with radius r3m is used to control the flow of water through a canal.the height of
How to calculate the principle of shoring system in formwork analysis when the secondly floor upper has been poured?
A computer technician can handle on average 5 service calls per day. The cost of adding a technician (C1) is $200 per day and the estimated cost of waiting per incident (C2) is $250 per day.
Calculate the primary consolidation settlement for the CH layer, assuming that it is normally consolidated with a water content of 70% and a compression index of 0.25.
In magnetic tape recording, the tape is subjected to tension while it is guided along its path. Tension in the tape causes elastic deformation that results in slight changes in length of the domains on which information is stored.
A closed tank having a volume of 1.0 ft3 is filled with 0.15 lb of a gas. A pressure gage attached to the tank reads 12 psi when the gas temperature is 80? F. There is some question as to whether the gas in the tank is oxygen or helium. Which do you ..
If the coordinate direction angles for F3 are a=120degrees, b=45degrees, y=60degrees, determine the magnitude and coordinate direction angles of the resultant force acting on the eyebolt.
The GNSS determined height of a station is 284.097 m. The geoid height at the point is -30.052 m. What is the elevation of the point?
