An insulated rigid tank is divided into two compartments by a partition. One compartment contains 2.5 kmol of CO2 at 27°C and 200 kPa, and the other compartment contains 7.5 kmol of H2 gas at 40°C and 400 kPa. Now the partition is removed, and the two gases are allowed to mix. Determine (a) the mixture temperature and (b) the mixture pressure after equilibrium has been established. Assume constant specific heats at room temperature for both gases.
what is the difference between normal stress and allowable shear stress. What is the difference between axial and hoop stress and how do you calculate tensile force per mm.
Assuming the kinetic and potential energy effects to be negligible, determine A) the mass flow rate in kg/s B) the temperature at the exit of the turbine, in C C) the power developed by the turbine in kW
A thin-walled cylindrical tank of radius r is subjected simultaneously to internal pressure p and a compressive force P through rigid end plates. Determine the magnitude of force P to produce pure shear in the cylindrical wall.
A u-tube manometer is used to measure the pressure of a vessel under vacuum. Assume the manometer is open to atmospheric pressure (101.325 kPa) and the density of the fluid in the manometer is 12 g/cm3.
The volume of the system is doubled from 1 m^3 to 2 m^3 while 200 kJ of heat is added to the system. If no work is done except for the boundary displacement work and the pressure remains constant at 101.3 kPa (1 atm) throughout the process,
develop a spreadsheet application that will display in a table the values of modulus of elasticity Ec for concrete having unit weight ranging from 95 pcf to 155 pcf (in steps of 5 pcf) and compressive strength ranging from 3500 to 7000 psi
calculate the critical depth of a circular concrete pipe with a diameter of 42 inches, a Manning's Number of .014, a slope of .025% and a flow rate of 10 CFS (cubic feet per second). The radius is 3.55 and normal depth is 25 inches
A pile resists the tension developed by three stay cables for a major for a tent (membrane) structure. Assuming no bending is desired in the pile (no resultant horizontal componenet), what is the magnitude of the force S if the and (theta sub S)
The following observations were made in an experiment for determining of dielectric strength of transformer oil. Determine the power law equation:
suppose you apply a force of 14.4 N to a spring and it stretches 2.4 cm. what is the spring constant?
A hydraulic jump is observed to occur in a channel with a mild slope at a flow rate of 20cfs/ft. If the depth before the jump is 1 ft, determine the depth after the jump.
A water sample has bucarbonate concentration of 220 mg/l ( HCO3- )and the PH of the water is 7.9 > Express the approximate alkalinityof this water as mg/l of CaCO3
