Each of the following either (a) violates the first law, (b) violates the second law, or (c) is correct. For each indicate which law (if any) is violated. Justify your answers with appropriate calculations
A] During an isothermal process a closed system of a perfect gas does 77,816.9ft-lbf of work. Heat transfer of 100 btuto the system takes place during the process.
B] A gas expands adiabatically through a nozzle. The enthalpy and velocity leaving the nozzle are each greater than those entering the nozzle.
C] Cooling water leaves a steam condenser at 150 F. the steam entering the condenser is at 1 psia and quality of 91.7percent.
Soil A is micaceous with an average grain relative density of 2.80, and has a high plasticity in its fine fraction. The ground quartz-feldspathic B is, with an average relative density of 2.65 and fine grains of low plasticity.
The flowrate (q) per unit lenght (ft^2/s) over the spillway shown below is a fuction of the upstream heah H, the acceleration due to gravity g, and the spillway height P.
Nairobi has a birth rate of 3.3 individuals per individual per year and a death rate of 3.2 individuals per individual per year. If the carrying capacity were 105, what would the population be in 25 years
Calculate the percentage of change in total volume with respect to its initial volume when a specimen of this clay is completely dried from a water content of 80%. Assume that the clay remains saturated from liquid limit to shrinkage limit.
The river flow at an upstream gauging station is measured to be 1500 m3/s, and at another gauging station 3 km downstream, the discharge is measured to be 750 m3/s at the same instant of time.
A square footing 2 meters by 2 meters is to be constructed 1.22 meters below the ground surface. The groundwater table is located 1.82 meters below the ground surface.
A -2.8% grade line meets a +3.6% grade line at station 125+00 at elevation of 1631.04. Assuming a length of curve is 650feet, compute the elevation and station of the BVC (PVC) and the EVC (PVT).
Three completely mixed stabilization ponds are connected in series, and the system removes 99.998% from the total coliform count of the influent to the first pond. In stabilization ponds, coliform bacteria are removed by a first-order process
A centrifugal pump is used to pump Vodka (S.G. 0.8) at a rate of 20 gallons per minute to the top of a 30 foot tall tank. The owner wants to use the same pump to pump orange juice (S.G. 1.1). Explain how this change in fluid will affect:
The aquifer characteristics are: Ambient temperature=8 oC Hydraulic conductivity = 123 ft/day Hydraulic gradient = 0.00091 ft/ft Effective porosity = 0.31 Total organic carbon = 198 mg/kg Bulk density = 1.65 g/cm3
Base course aggregate has a target dry density of 119.7 Ib/cu ft in place. It will be laid down and compacted in a rectangular street repair area of 2000 ft by 48 ft by 6 in.
Heat exchangers can be arranged in either counter current mode (where the hot and cold fluids are fed at opposite ends of the heat exchanger) or co-current mode (where the hot and cold fluids are fed at the same inlet as the heat exchanger). Sketch e..
