Assuming that the nozzle is well insulated and operating at steady state and that the air behaves as an ideal gas, calculate (a) the mass flow rate of air in kg/s, (b) the exit area of the nozzle in m^2,
A conical tube of length 8 m fixed vertically with its smaller end upwards. The velocity head and pressure head at upper ends are 1.27 m and 2.50 m respectively.
Determine the deflection of the right end of the pointer and the maximum deflection of the beam.
Find the length and width of a square basin for virus disinfection of a flow of 6 MGD. You may assume a depth of 5 ft, a C•t product of 10 (mg/L) •min for 1.5-log removal, and a target free chlorine residual of 0.6 mg/L.
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..
A civil engineering student contends that 60 mph is safe in a van because of the higher driver's eye height. If all other design inputs are standard, what must the driver's eye height in the van be for the student's claim to be valid
Estimate the required surface area (A), and the diameter and the depth of the tank.
A 2000-lb wheel load is to be supported by aggregate over soil with a maximum bearing pressure of 1000 lb/sqft. What depth of aggregate is needed if the angle theta is 40 degrees?
1. What does the acronym ANSI stand for Stands for American National Standards Institute 2. What is the purpose of a titleblock The purpose of a title block is for give us enough information about the project.
The position of a particle moving along an x axis is given by x = 17t2 - 5.0t3, where x is in meters and t is in seconds. (a) Determine the position, velocity, and acceleration of the particle at t = 3.0 s. x = m v = m/s a = m/s2
A common commercial process for the production of so-called "Electronic Grade Silicon" (EGS) is the Siemens process (see figure below). EGS is of ultra-high purity, enough to be used for fabrication of microchips.
