a spherical container with a diameter of 50 ft made of steel plate holding a gas at 50 psi. with a tensile strength of 16000. What is the required thickness of the plate?
A larger-diameter pipeline will cost $2.1 million installed, but its operating cost will be only $8000 per month. Which pipe size is more economical at an interest rate of 1% per month on the basis of an annual worth analysis
Derive an equation that allows you to compute the diameter of the drain hole for a desired steady water height in the tank for the design condition inflow and pumping rates.
You plan to use a tank of total volume V= 10 m3 to remove a contaminant at concentration Cin = 1 g/m3 from a waste stream with a flow rate of Q = 1 m3/h. The reaction is first order with a rate constant k1 = 0.5 h-1.
determine the maximum horizontal distance that a projectile will have at a height of 60 m above the orgin if it is fired at an angle at 70 degrees from the horizontal with a velocity of 50 m/s
At what depth would the vertical effective stress in a deep deposit of clay be 100 kpa, if e=1.1 The ground water level is a 1 m delow ground surface and S=95% above the groundwater level. Neglect pore air pressure.
A waste mixture contains a variety of volatile organic compounds, nonvolatile organics, metals, and sandy soil. In a vitrification treatment, a. which of these materials are likely to be retained in the resulting solid
how large a sample must we take in order to be a) 95% b) 90% c) 99 d) 99.73% confident that the error in the estimated mean lifetime will not exceed 20 hours.
air enters a turbine operating at steady state at 8 bar, 1127 C and exits at 1.5 bar, 347 C. The heat transfer from the turbine to its surroundings is 10 kJ/kg of air flowing through the turbine.
A geothermal power uses hot water (185oF) as a heat source and the cold water from a close by lake (60oF) as a heat sink. The basic operating system is a close loop ammonia efficiency of the cycle that powers turbine-driven electric generator (100..
An 8-inch water main with a flow rate of 14 ft3/sec raises 100-feet. At the beginning of the main the pressure is 110 psig and drops to 50-psig at the end. For this water main calculate the head loss
The discharge of the river at the basin outlet is measured at an avarage of 650 cfs. assuming that the charge in storage for the system is essentially zero, estimate the ET losses for the area in inches and centimeters for the year
Include a description of the types of property markers used as well as any problems a surveyor may encounter in this process in your explanation. In addition, discuss the minimum alignment required to establish the centerline
