In an axial.flow compressor, overall stagnation pressure ratio achieved is 4 and overall stagnation isentropic efficiency is 85%. The inlet stagnation pressure and temperature are 1 bar and 300 K, respectively. The mean blade velocity is 180 m/s. The degree of reaction is 50% at mean radius with relative air angles of 12° and 32° at rotor inlet and outlet, respectively. The work done factor […]
A double pipe heat exchanger is constructed of 0.287 cm thick steel tubing with 2.09 cm inner tube and 2.66 cm outer tube. The inside and the outside coefficients of heat transfer are 1 135 W/ m 2 .K and 5677 W/m2 .K, respectively, and the fouling factor is 9.98 x 105 m 2 .K/W. Calculate the overall coefficient of heat transfer.
Which of the following statements is correct? a. Total surplus is the sum of consumer and producer surplus. b. Deadweight loss is the net loss of both consumer and producer surplus. c. Deadweight loss is a measure of market ineffi ciency. d. All of the above. In Exhibit A-7, suppose fi rms devote resources suffi cient to produce 4,000 units of good X per month. […]

Show that it is possible to ensure that a dependency-preserving decomposition into 3NF is a lossless decomposition by guaranteeing that at least one schema contains a candidate key for the schema being decomposed. (Hint: Show that the join of all the projections onto the schemas of the decomposition cannot have more tuples than the original relation.)

The Maximum Amount is a company that specializes in making fashionable clothes in large sizes for plus-size people. A survey was performed for the Maximum Amount, and a regression analysis was run on some of the data. Of interest in this analysis was the possible relationship between self-esteem (dependent variable) and number of Maximum Amount articles purchased last year (independent variables). Self-esteem was measured on […]
