Design a steam power cycle that can achieve a cycle thermal efficiency of at least 40 percent under the conditions that all turbines have isentropic efficiencies of 85 percent and all pumps have isentropic efficiencies of 60 percent. Prepare an engineering report describing your design. Your design report must include, but is not limited to, the following: (a) Discussion of various cycles attempted to meet the goal as well as the positive and negative aspects of your design. (b) System figures and T-s diagrams with labeled states and temperature, pressure, enthalpy, and entropy information for your design. (c) Sample calculations. (d) Propose ONE (1) possible application of your design with complete/comprehensive discussions (e) Propose ideas or solutions on how to increase the efficiency of the system
Calculate the specific enthalpy at the compressor outlet. Include in your calculations the changes in kinetic and potential energy.
Determine the minimum coefficient of static friction between the crate and the truck so that the crate does not slide relative to the truck.
the system on site is a pressure sand filter with a service curve. the filter is backwashed using the feed pump at a
What are stress concentrations, what causes them, and why should engineers be concerned about them?
a 13.2-N force P is applied to the lever which controls the auger of a snowblower. Determine the moment of P about A when alpha is equal to 30 degrees.
(a) determine the first three natural frequencies of the tube (b) Draw the standing wave pattern for both pressure and velocity (c) repeat parts a and b if the right one end is attached to an orifice (Hint: consider the impedance of the orifice to..
In a tubular low pressure chemical vapor deposition (LPCVD) reactor, gas is introduced at one end at a rate of 75 torr-L/min. At the other end is a vacuum pump of a speed Sp. If the reactor must operate at 1 torr, what value of Sp is required?
A 4 m diameter sphere is embedded in insulation. The sphere contains a liquid-ice mixture maintained at 0 deg C. The ambient temperature surrounding the insulation is 25 deg C.
The hydrogen spectrum has a red line at 656 nm and a blue line at 434 nm. What is the first order angular separations between these two spectral lines obtained with a diffraction grating that has 4500 lines per centimeter?
What is the total rate of heat transfer to the air? What is the pressure drop associated with the airflow?
Determine the crack growth for cycle #3 using Wheeler's retardation model (m=2)-finite width correction factor for SIF
A horizontal cantilever of length L supports a load W, uniformly distributed along its length. the cantilever is proped to the level of the fixed end at a distance 3/4 L from that end. Determine the load on the prop.
