Weibull distribution: From an analysis of wind speed data (hourly interval average, taken over a 1 year period), the Weibull parameters are determined to be c = 6 m/s and k = 1.8 at a potential WT site.The Weibull PDF is given by
a. Estimate the number of hours per year that the wind speed will be between uB = 6.5 and uA = 7.5 m/s during the year.
b. Estimate the number of hours per year that the wind speed is above 16 m/s.
Assume 2a = 1 cm, h = 0.5 cm, 2d = 10 cm, and that the arms have equal length 7 cm. What is the angle of arm 1 rocking?
collar c moves along a circular guide with radius R=2ft with a constant speed v=18ft/s. at the instant, the bars AB and BC are vertical and horizontal respectively. Letting L=4ft and H=5ft, determine the angular acceleration of the bars AB and BC ..
An automobile weighing 2500 lbf increases its gravitational potential energy by 2.25x10^4 Btu in going from an elevation of 5183 ft in Denver to the highest elevation on Trail Ridge Road in the Rocky Mountains. What is the elevation at the high point..
A 3.03-ft3 rigid tank contains saturated refrigerant- 134a at 100 psia. Initially, 17 percent of the volume is occupied by liquid and the rest by vapor. A valve at the top of the tank is now opened, and vapor is allowed to escape slowly from the tank..
Draw flow diagrams of unit operations for producing from raw MSW the following products: a. RDF-1 b. RDF-2 c. RDF-3 d. RDF-4 No other materials are to be recovered, and the purity of the fuels is important.
If the frequency of motion of the block is found to be determine the coefficient of friction between the block and the rollers.
a vehicle is to be parked over night in the open away from large surrounding objects. it is desired to know if dew or
Ten kilograms of water at 15° C and 700 kPa are contained in a cylinder as shown. Heat is transferred slowly causing the piston to rise. Determine the heat transfer and work done if the final condition is saturated vapor. Show the process on a T-v di..
a rigid well insulated container is outfitted with a moveable but frictionless partition that separates two sides but
Consider a concentric pipe with inner radius of Rin and outer radius of Rout. The flow is laminar and in the direction of the axis of the pipes. Obtain the velocity profile for this geometry, u(r); and also expressions for the maximum velocity, the m..
This activity will involve researching a concept or component related to the turbine engine lubrication system. The concept can be on the different types of synthetic oils used in turbine engines or an explanation of oil analysis. It can be on a c..
A liquid/vapor water mixture with 2.7 lbm and a pressure of 1000 psia is heated at constant pressure until the temp is 600ºF. What is the final total enthalpy of the water, in BTUs?
