Carbon dioxide gas contained within a piston-cylinder assembly undergoes three processes in series. Sketch the processes on P-V coordinates and evaluate the work for each process in kJ. Process 1-2: Expansion from P1= 5 bar, V1=.2 m^3 to v2= 1 m^3 during which the pressure volume relationship is PV=constant. Process 2-3: Constant volume heating from 2 to state 3 where P3= 5 bar. Process 3-1: constant pressure compression to the initial state.
The two outer bars (material A) are identical. The cross- sectional area of the middle bar (material B) is 31.544% larger than the cross- sectional area of one of the outer bars. Also, the modulus of elasticity of material A is twice that of mater..
two solid cylindrical rods are joined at B and loaded as shown rod AB is made of steel(E=200 GPa) and rod BC of brass ( E = 105GPa) determine a) the total deformation of composite rod ABC, b) the deflection of point B
What is the contact time (min) required to achieve a log-3 deactivation of Giardia in water of 10 °C temperature, at pH 7, if the chlorine concentration is 2.2 mg/L?
A specimen of saturated soil has a water content of 145 percent and a total unit weight of 84 pcf. Find the void ratio and specific gravity of solids.
what are the main points which create necessity of new railway line? explain in detail different types of surveys conducted in railway work.
A 40 cm diameter well has been constructed in a water-table aquifer. A pump capable of continuous discharge at 600 m3/day has been installed to test the well. Observation wells are located 10 meter and 50 meters from the pumped well. After pumping co..
A gas bubble is formed at the tip of a small tube which is completely immersed in a large body of liquid. The bubble remains in contact with the open end of the tube in a way that allows us to control the pressure P inside the bubble.
Air pollution in a city is caused by the following four sources: vehicle exhaust (V), industrial exhaust (I), dust (D), and pollen from plants and trees (T). On a particular day, the likelihood of air pollution caused by these sources is 4:3:2:1, ..
Based on given soil data. Soil is a loam with grain the #200sieve. The Liquid Limit = 29, Plastic Limit = 24, friction angleφ = 25 degree, cohesion c = 0.21 tons/sf, unit weight γ=124lb/ft3.
Determine the surface area of a primary settling tank sized to be handle a maximum hourly flow of 0.570 m3/s at an overflow rate of 60 m/day.If the effective tank depth is 3.0 m
To maintain a pressure of 300kPa at point 2, what the 15 C water is flowing at 0.5 L/s, what pressure must be provided at point 1 if you neglect friction
What is the smallest particle size (density 2.65 g/cm3) that will be removed in a horizontal grit chamber 10 m long and 1.0 m deep if the flow rate is 1000 m3/hr. Assume the temperature of the water is 25°C.
