Ggest the most suitable generic software process model that cab be useful as a basis for the development of following systems. Provide reasons for your answers.
a. A complex real time system whose requirements can be relatively easily identified and are stable.
b. A website for university library. Requirements are vague and are likely to change in the future.
c. An order processing system with a website for local business. Requirements are vague but unlikely
to change in the future and thus stable.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Determine the stoichiometric and actual air-fuel ratios and the mole flue gas composition for combustion with 15% excess air for raw indiana, pennsylvania raw coal.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
