1. A constant-pressure piston/cylinder contains 2 kg of water at 5 MPa and 100?C. Heat is added from a reservoir at 600?C to the water until it reaches 600?C. Find the total irreversibility in the process.
2. A constant "flow" of steel parts at 2 kg/s at 20?C goes into a furnace, where the parts are heat treated to 900?C by a source at an average of 1250 K. Find the reversible work and the irreversibility in this process.
Consider a DVD To protect sensitive information within the storage medium, a vwery thin film of reactive polymer is embedded within the polycarbonate at a distance of d= 0.5 mm from the surface.
For the fully developed flow of water in a smooth 0.15-m pipe at a rate of 0:006m3/s, determine the thickness of a. the laminar sublayer; b. the buffer layer; c. the turbulent core.
Determine if a simple supported W 12x26 (A36 steel) beam has the capacity to support loads that produce 50 kips of live-load shear and 20 kips of dead-load shera.
What is the maximum thermal efficiency this thermoelectric generator can have?
Wrought iron pipe is 5 cents more than galvanized pipe. The headloss per meter for wrought iron pipe (.02 m diameter) hL= 0.087m for (0.15 m diameter) hL= 0.387m. The headloss per meter for galvanized iron pipe
A uniform steel ring 600 mm in diameter has a mass of 50 kg and is lifted by the three cables, each 500 mm long, attached at points A, B, and C as shown. Compute the tension in each cable
A meat packing plant manager is trying to decide between twodifferent methods for cooling cooked hams. the spray methodinvolves spraying water over the hams until the ham temperature isreduced to 30 degrees Celcius. With this method approximately 80l..
Output the water surface pro le plots with all 3 discharges, including the water surface, energy grade line, and critical depth line. Hint: You only need to de ne 3 cross-sections (1 upstream one at the slope break, and 1 at the downstream locatio..
What is the difference between determinate structure and indeterminate structure?
What would be the tensile proof force in newtons (N) in a machine screw having a major diameter of 4 mm with standard fine threads if it is made from steel having a metric strength grade of 8.6?
given a tree t of nodes such that each node contains a number. a set of nodes s is an independent set of t iff no node
What type of foundation do you think should be used in this situation (keeping in mind the relative weight of the building)? Now look at the foundation drawings. What type is actually used? Why?
