1. How can solid solutions form in ceramic systems?
2. Do we need 100% solid solubility to form a solid solution of one material in another?
3. What is a copolymer? What is the advantage to forming copolymers?
4. What is the ABS copolymer? State some of the applications of this material.
An ideal vapor-compression refrigeration cycle operates at steady state with Refrigerant 134a as the working fluid. Saturated vapor enters the compressor at 2 bar, and saturated liquid exits the condenser at 8 bar. The mass flow rate of refrigeran..
1. Design a combinational logic circuit which will add two 4-bit binary numbers. 2. Minimize the expression described in the truth table of Figure P12.50, and draw the circuit.
a frictionless poston-cylinder device initially contains air at 100 kpa and 0.15m3. at this state a linear spring f
Suppose that there is one input, labor (L), and that there are two outputs, goods 1 and 2. The production function for good 1 is y1 = f1(L), and the production function for good 2 is y2 = f2(L).
a rigid tank initially contains 3 kg of air at 500 kpa 290k. the tank is connected by a valve to a piston-cylinder
Suppose the pipe diameter is 5 cm and the rod is a cylinder of diameter 8 mm. If the sensor reads 5400 counts per minute, estimate the volume flow rate of water in m3 /h. How might the meter react to other liquids?
A common problem with brazed or soldered joints is galvanic corrosion, since the joint usually involves dissimilar metals in direct metal-to-metal electrical contact.
Nitrogen is compressed in a piston-cylinder starting with a volume of 1 m3 and a temperature of 27oC to a final state where the temperature is -23oC. If the specific entropy change is -0.28kJ/kgoK what is the final volume?
Assuming nucleate boiling conditions calculate the temperature of the bottom surface of the pan.
a bullet of mass 81gm and moving with a velocity of 300msec is fired into a log of wood and it penetrates to a depth of
consider a regenerative rankine cycle with a 600c and 4-mpa throttle a 5-kpa condenser and an open feedwater heater at
The figure shows a typical V-truss A-B from a building crane. In this exercise the truss is considered as plane. The truss is supported by a fixed hinge at A and an inclined tension bar DC, connected to the head of the truss at C. It carries the v..
