A given convergent nozzle operates so that it is choked with stagnation inlet flow properties of 400 kPa, 400 K. To increase the flow, a reversible adiabatic compressor is added before the nozzle to increase the stagnation flow pressure to 500 kPa. What happens to the flow rate?
A minimum contact time of 30 min is required to reduce the pathogen concentration from 100 pathogens/L to below 1 pathogen/L through a first-order decay process. You plan on treating water at a rate of 1,000 gal/min.
A dye streak was started at a point in the flow field at time t=0, and the path of a particle in the fluid was also traced from that same point starting at the same time. Draw the streakline, pathline of the particle, and streamlines at time t=10s..
determine the rate of heat gain of the room, in Btu/h, when the air conditioner is running continuously to maintain a constant room temperature.
Determine the acceleration of the initially stationary 20-kg body when the 50-N force P is applied. The small wheels at B are ideal, and the feet at A are small.
If inflation pushes the price level up by 10 percent, what will be the real value of your savings? What is the real value of your savings if the price level declines by 10 percent?
A simple "box-like" canoe has outer dimensions of 15.0 ft in length, 2.0 ft in width, and 1.0 ft in depth. The canoe shell is made of concrete with a specific weight of 58.0 lbs/ft^3 and contains 15.0 lbs of steel reinforcement with negligible volume..
Are installed together? Show calculations to justify your answer and sketch a specific energydiagram to illustrate the process of changes in flow depth in eachcase.
A reaction known to release 1.78 kJ of heat takes place in a calorimeter containing 0.100L of solution and the temperature rose by 3.65 degrees C. The calorimeter was then rinsed out and emptied. To the empty calorimeter was placed a small piece of c..
A city is considering a 3 stage membrane system to treat brackish groundwater at its water treatment plant, WTP (Qf=1000m^3/d, Cf=2000mg/L TDS). Each stage can perform 60 % water recovery (Qp/Cf) and 90% salt rejection (1-Cp/Cf)
Suppose that from the past experience a professor knows that the test score of a student taking his final examination is arandom variable with mean 70 and standarddeviation 85
Explain the meaning of the reliability index,β, and how it relates to failure / survival inthe context of bridge design? What is the value ofβ we use in design?
