Question 1 a. An approximately circular catchment area of 31.195 km catchment area is located in a desert region with no vegetation. The average annual precipitation is 200 mm. The average annual outflow from the catchment is 43200 m/d. Compute the average annual evaporation from the catchment in mm and the average daily evaporation in m/d. In this catchment area, an irrigation project was developed covering the size of the trapezoid ABCD. The coordinates A, B, C and Dare (3000,...
A rural catchment area of 5,5 km² has an average slope of 3% is covered by grass with clay soil. The length of the main watercourse is 2 km with an average slope of 2% and overland flow can be ignored. Calculate the peak run-off by means of the Rational method at the time when the catchment received 40mm of rain.
A hydroelectric power plant has a head of 57 m and spills water at 15 megatonnes of water per day for 20 days. The surface area of the reservoir is 2.0 km^2. What's the power produced by this power plant in MW?
a) A hydro-electric power station has a reservoir of area 2.4 square kilometre and capacity 5milliom cubic metres. the effective haed of water is 100m, the penstock, turbine and generator efficiencies are 955,90% and 85% respectively. i) Calculate the total electrical energy that can be generated from the power station ii) if the load of 15MW has been supplied for 3 hours, find the fall in reservoir level b) Determine the most economical conductor cross section area to transmit a...
(b) The daily design load curve of a residential area is given in the table below. The hydropower facility providing the power has an effective head of 15 m and a plant efficiency of 0.85. What is the minimum daily flow (m3/s) that could meet the demand? What is the minimum required storage capacity (within-day storage) to meet the peak load? If the daily flowrate were 320m3/s, what would be the minimum required storage capacity? Would there be some water...
A small coastal town in Queensland is subject to an increasing permanent population and also a transient influx of tourists during the summer period. Council already receives frequent complaints of restricted water supply. The water supply system comprises a rising trunk main from the treatment plant A to the service reservoir B, the service reservoir, and service mains to the consumption areas. Two consumption areas C and D at different elevations are gravity supplied from the service reservoir. The service...
Design a heat exchanger for a gas turbine exhaust A paper mill has just purchased a 5.7 MW gas turbine for electrical power generation. To increase the overall plant efficiency and reduce the payback time it has been decided to use the exhaust gases to heat water in a heat exchanger. The company requires 12.7 tonnes/hr of steam at a pressure of 18.9 Bar and at a temperature of 315oC. The temperature and pressure at inlet to the heat exchanger...
Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...
Discussion Questions: 1. What is the purpose of a distribution center? 2. Why does Cameron have eight warehouses? Why do you think Kelly believes six warehouses is better than eight? 3. What is the cost of holding inventory at Cameron? 4. Why should the decision to invest in inventory be different from investing in capital? 5. Do you think it is prudent to evaluate the future of the Atlanta warehouse independently from consideration of the other seven warehouses in the...
