Define types of temporary works required to deal with stability and groundwater problems in the London college project.
A room 7m x 6m x 3m high is to be electically heated to maintain the inside temperature at 20 C, when it is 0 C outside. The room has 2 windows each 1.2m x 1.8m and a sliding glass door 2.4m x 2.1m. The transmission coefficients u in Wm^2/C are given..
A mass of 5 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 125 kPa. Initially, 2 kg of the water is in the liquid phase and the rest is in the vapor phase.
Due to a crash at a railroad crossing, an overpass is to be constructed on an existing level highway. the existing highway has a design speed of 50 mi/h.
The water table is 7m below the surface of the sand. The saturated unit weight of the sand is 19kN/m3 and that of the clay 20kN/m3; the unit weight of the sand above the water table is 16kN/m3.
A steel bar of length 30 inches and circular cross section whose diameter varies linearly from 0.50 inches at one end to 0.75 inches at the other is subjected to an axial tensile force of 4.5 kip. Find the change in length of the bar.
Water flows through a 200 m long ,30 cm diameter steel pipe with surface roughness 0.046 mm at a rate of 0.25 m^3/s .Find the pressure(P2)considering both friction and minor losses if P1=500 kPa;Z1=20m; Z2=10m ; L=200m ; K=10.0 ; D=30 cm?
Northern Tundra Telephone (NIT) has received a contract to install emergency phones along a new 100-mile section of the Snow-Moose Turnpike. Fifty emergency phone systems will be installed about 2 miles apart.
This project is expected to have a first cost of $2,000,000 and an annual maintenance cost of $50,000. In addition, major repairs costing $250,000 will be required after 25 years and each 15 years thereafter.
The following data are obtained for a particular reach of the Provo river in Utah: cross sectional area A = 183 ft2, free surface width = 55 ft, average depth = 3.3 ft, Rh = 3.32 ft, V = 6.56 ft/s, length of the reach = 116 ft, and elevation drop ..
Determine the maximum radius R (to the nearest 10m) so that there are at least 200m of tangent between the two curve systems and determine the Pl, ST., and CPI stations
A pumping well of 0.75-m radius fully penetrates an unconfined aquifer of 24-m thickness and produces at a rate of 10 L/s. After a long period of pumping well is 1.6 m. The drawdown in another observation well 60 m from the pumping wel
