Propane gas enters a continuous adiabatic heat exchanger' at 40°C and 250 kPa and exits at 240°C superheated steam at 300°C and 5.0 bar enters the exchanger flowing counter currently to the propane and exits as a saturated liquid at the same pressure.(a) Taking as a basis 100 mol of propane fed to the exchanger, draw and label a process flowchart. Include in your labeling the volume of propane fed (m3), the mass of steam fed (kg), and the volume of steam fed (m3).
A ball is thrown vertically up with a velocity of 91 ft/sec at the edge of a 190-ft cliff. Calculate (a) the height h to which the ball rises and (b) the total time t after release for the ball to reach the bottom of the cliff.
Advanced Stress Analysis Assignment
A collar B of weght W can move freely along thevertical rod. The constant of the spring is k and the spring is unstretched when theta=0. Derive an equation in W thrta k and l that must be satisfied when h collar is in equilibrium.
the cylinder is made from steel where yield stress= 240 MPa and v=0.3. Subsequently sketch the hoop and radial stresses in the wall of the cylinder.
Use a suitable method to predict the racS,T variation along these plates when a= e= 0.1, 0.5, and 0.8 and emissions and reflections are diffuse.
The velocity profiles at locations x=0.1, 0.30 and 0.5. Plot contours of u-velocity and v-velocity. How many iterations did it take to get your solution?
Fluid/Dam Pressure, Compare the pressure force exerted on the face of two dams that hold a fresh water of 1000 Kg/m^3 density and a salty water of 1030 Kg/m^3
Find graphically the forces f1 and f2 in the crane. The triangle is standing up with a 90 degree angle next to the wall on top, with f1 pointing towards it
The assessment to design a substation and the associated protection System.
the manometer shown above in problem 1 above contains water and kerosene. with both tubes open to the atmosphere, the free surface elevations differ by H=20mm determine the elevation difference when a pressure of 98.0 Pa is applied to the right.
Given that an activity's normal time and cost are 10 days and $400 and its crash time and cost are 5 days and $800, what is the activity's slope?
