1.Determine the critical load of a steel tube that is 5 m long and has a 100-mm outer diameter and a 16-mm wall thickness. Use E = 200 GPa.

2.Carbon dioxide flows in a 75 mm diameter PVC pipe at 0.014 kg/s at a pressure of 345 kN/m^2/s abs and a temperature of 10 degrees C. Calculate the head loss in 500 m of pipe.

3.A composite beam is fabricated by connecting two W6 x 20 rolled-steel members, using bolts of 5/8-in. diameter spaced longitudinally every 6 in. Knowing that the average allowable shearing stress in the bolts is 10.5 ksi, determine the largest allowable vertical shear in the beam.

4.Air at 60°F and 40 psia flows in a 4-in.-diameter pipe with a mass flux of 0.2 slug/sec. The pipe undergoes a conversion to a 2 in. by 3 in. rectan- gular duct in which T ?? 150°F and p ? 7 psia. Calculate the velocity in each section.

#### What will be the discharge at a depth of 50cm in the pipe

A concrete sewer pipe 1m in diameter is laid so it has a drop in elevation of 30cm per 300m of length. If sewage (assume the properties are the same as those of water) flows at a depth of 50cm in the pipe,

#### Net rate of flow of linear momentum via control surface

Measurements indicate that to cause this flow the force acting on the contents of the control volume is 40i lb. Determine the net rate of flow of linear momentum through the control surface.

#### Discuss the soil mechanics aspects of situation

Should the laboratory test programme focus on producing values of c' and Ø', or Su (undrained shear strength)? Explain - Discuss the soil mechanics aspects of situation and determine whether the risk of failure in the soil is increasing, decreas..

#### What is the maximum column load in kips that could be placed

What is the maximum column load in kips that could be placed on a 4-ft square temporary footing on a sand for which the standard resistance is about N=15 and the water table is at the surface A factor of safety of 2 is to be maintained against bea..

#### Determine the height from the ground at which ball pass

Ball A is thrown vertically upward from the top of a 20-{\rm m}-high-building with an initial velocity of 3m/s . At the same instant another ball B is thrown upward from the ground with an initial velocity of 16m/s .

#### Estimate the change in pressure over 100 m of pipeline

Water at 20 degrees flows at a velocity of (V =) 2 m/s in a (D =) 250-mm diameter horizontal ductile iron pipe. Estimate the friction factor f in the pipe, and state whether the pipe is hydraulically smooth or rough.

#### Determine the filtration rate at the depth of the layer

The absolute viscosity and density of water are 1.4X10^-3 Pa-s and 998 kg/m^3, respectively. For a head loss of 0.1 m, determine the filtration rate (m/d) if the depth of this layer of sane is 0.1m

#### Determine the storage content at the end of 30 days

During a particular 30-day period, the streamflow flowing into a reservoir averaged 5.0 m3/s. Water supply withdrawals from the reservoir averaged 136 mgd. The only other outflow from the reservoir was 9.4 cm of evaporation from the water surface.
