A smooth constriction is installed across a flume. Flow conditions in this flume is such that the free surface level drops (water depth reduces) within the constriction. How do you classify the flow conditions in the flume upstream of the hump? Explain the reasons for your classification and free surface change using the concepts of specific energy and total energy. Use the E-Y diagram to support your explanation.
The beam and attached hoisting mechanism together weigh 2400 lb with center of gravity at G. If the initial acceleration α of point P on the hoisting cable is 20ft/sec2 calculate the corresponding reaction at the support A
A 6.22-kg object passes through the origin at time t = 0 such that its x component of velocity is 5.45 m/s and its y component of velocity is -2.88 m/s. (a) What is the kinetic energy of the object at this time
Assume the only products are CO2, H2O, CO and N2. State results as the CO molar fraction of both wet and dry exhaust products ( wet exhaust products include H2) and dry exhaust products exclude it).
