Worker needs to enter a confined space to tighten the packing on a leaking argon valve.
a. Would you require a confined space entry permit to be used? Why or why not? b. Describe two procedures that could be used to isolate the argon line and valve prior to starting work.
If the purlins are spaced 4 ft and the bents are spaced 25 ft apart, determine the distributed loading that acts along the purlin DF and the loadings that act on the bent at A,B,C,D, and E.
A 50-kg iron block at 80C os dropped into an insulated tank that contains 0.5m^3 of liquid water at 25C. determine the temperature when thermal equilibrium is reached.
CALCULATE THE REQUIRED DIAMETER OF STEEL TIE RODS NECESSARY TO SUPPORT A BALCONY. EACH ROD, SUSPENDED FROM A ROOF TRUSS, SUPPORTS A FLOOR AREA OF 7.0m^2. THE COMBINED BALCONT FLOOR LOAD IS 10.5 kPa
hree wells are drilled in an unconfined aquifer with the following coordinates and observed heads: Well 1: 0,200 (meters) 50 (meters) Well 2: 240,130 54 Well 3: 140, 320 63 (a) Find the magnitude and direction of the hydraulic gradient.
If the BOD5 of the river below the mill outfall must not exceed 5 mg/L, what percent removal of organic matter (BOD5) is required by the mill to meet this requirement?
A rigid beam (AB), 12 feet in length, with a point load of 9 kips (4 feet from A) is resting on two short steel rods (AC & BD). Diameter of Rod AC is 1 inch, Rod BD diameter is 2 inches.
Shear and normal stresses on aplane that is 37 degrees from horizontal
A rectangular channel 5 m wide carries a discharge of 10 m^3/s at a uniform depth of 3 m. The channel is running on a slope of 0.0025 m/m. Estimate wall shear stress and friction velocity. Assume the density of flowing water as 1000 kg/m^3.
Employing the ideal gas model with constant specific heat ratio k, determine the temperature at the end of the process and the amounts of work and the heat transfer per unit mass in Btu/lb
The following data are obtained for a particular reach of the Provo river in Utah: cross sectional area A = 183 ft2, free surface width = 55 ft, average depth = 3.3 ft, Rh = 3.32 ft, V = 6.56 ft/s, length of the reach = 116 ft, and elevation drop ..
For the beam loading, (a) draw the shear and bending-moment diagrams, (b) determine the magnitude and location of the maximum absolute value of the bending moment.
