A Carnot engine receives 250 kW of heat from a heat-source reservoir at 798.15 K (525°C) and rejects heat to a heat-sink reservoir at 323.15 K (50°C). What are the power developed and the heat rejected?
Develop a project plan and schedule of tasks for each engineer. Be sure to allow sufficient time for equipment sizing, costing, and optimization. What intermediate deliverables would you specify to ensure that the project stays on track?
air at 4mpa and 3000c enters a will insulated turbine operating at steady state with negligible velocity. the air
For the segment Y3 to be turned on, develop the logic expression and find one possible logic circuit to realize the output in each case.
The activated carbon adsorbent has average bulk density 120 kg/m3 and heat capacity 0.7 J/g.°C. The solvent flammability limits in air are 2.5 to 12.0 vol% at 293 K and 1.2 to 16.0 vol% at 363 K.
A closed tank, 1 m3 in volume is filled with water at 1 bar 80 °C. A second identical tank contains 20 kg of steam at 20 bar. What is the mass of water in tank 1?
Mass transfer coefficient from a free water surface to an adjacent moving air stream has been found to be 0.015 kg/m2-s. Estimate the rate of evaporation from a surface of 1 m2 at a temperature of 28 oc into an air..
If the family of a patient in the intensive care unit submits the individual's living will document, should it be honored immediately or should there be a discussion between physicians and the family? Who should make the decision? Why?
Draw a schematic connection diagram as an autotransformer.
Three waveforms seen on an oscilloscope are shown in Figure P1.4.7. If the horizontal scale is set to 50 ms per division (500 ms for the entire screen width), and the vertical scale is set to 5 mV per division (±25 mV for the entire screen height ..
The scaling factor k must be such that the total probability is one. Therefore, we have k = 1/36. The table shows one instance where x + y >5, which is x = 3, y = 3. The probability is p = 9/36 = 1/4.
Develop a two-dimensional addressing system using a 6-to-64 decoder, a 64-word×128- bit matrix, and 16-input multiplexers. How many gates would such a system require?
Question - 1 In an oxygen -nitrogen mixture at 10 atmosphere and 25 oc , the concentration of oxygen at two places 0.2 cm apart are 10 and 20 volume percent respectively. The rate of diffusion of oxygen expressed as g /cm2 -hr for the case of unic..
