You will be creating your own building or use the real building data that you know of or have access to. Building description should include square footage, occupancy, schedule and type of HVAC systems including heating, cooling and ventilation. Also, utility bills (gas & electric) for one year (monthly usage).
Choose one or more energy efficient measure that you want to implement in your building.
For instance, lighting retrofit, heating system upgrade, AHU VAV retrofit etc.
Describe new technology; benefits, disadvantages if any etc.
Calculate energy savings, implementation costs and simple payback. You should be able to find some tips and calculations from the text book.
Midrange and amplitude components, A shaft is subjected to a completely reversed bending stress such that Xmax=40kpsi and Xmin=-40kpsi
the tank has a 180mm diameter and 12 mm wall thickness. knowing that the tank contains compressed air under a pressure of 8 Mpa, determine the magnitude t of applied torque for which the maximum normal stress in tank is 75 Mpa.
In order to increase production rate, a reactor setpoint was increased from 160 psig to 190 psig. The reactor pressure transmitter was recalibrated from 0- 200 psig to 0- 300 psig. What is the percent span for the old and new setpoints?
Define- hydraulic mean radius, hydraulic dept, section factor and most efficient dhannel cross section.
water contained in a closed, rigid tank, initially saturated vapor at 200C, is cooled to 100C. determine the initial and final pressure, each in bar. locate the initial and final states on a sketches of the p-v and T-v digrams.
Steady State Thermal analysis can be use to simulate and obtain results to support the design optimization / objectives
determine a) the angular accelerations of gears B and C, b) the accelerations of the points on gears B and C which are in contact when t = 0.5 s.
A reversible heat engine operates between 875 K and 310 K and drives a reversible refrigerator operating between 310 K and 225 K. the engine receives 2000 kJ of heat and the net work output from the arrangement equals 350 kJ. make calculations for..
Explain the characteristics of the Phugoid motion. What is the governing aerodynamic derivative which determines the convergence or otherwise of the motion?
A steady flow air compressor compresses 50 lb/min from 14 psia and 80 degrees F to a discharge state at 45 psia and 300 degrees F. Heat departs from the air only via circulating water that enters the jacket at 75 degrees F and leaves at 95 degrees..
Package Design Brief: Assume you are the packaging engineer for a large consumer products company. In this company, the Packaging Design Briefs are initiated by the marketing group and forwarded to the Package Engineering group.
assuming that the solid shaft has been replaced by a hollow shaft of the same cross-sectional area and with an inner diameter equal to half of its own outer diameter.
