When a plastics plant is redesigned, a tank exit is now facing the wrong direction and must be connected to a pipe of diameter D=0.2 m with a180o bend in a horizontal plane. Liquid with S=1.0 is to flow through the bend at 0.3 m3/s. The pressure in the liquid is 250 kPa gauge. The volume of the bend is 0.1 m3. The steel of the bend material weighs 51 kg. Neglecting friction or other losses in the pipe, what is the tension force in the bolts holding the bend in place?
A rod of steel is 20 m long at a temperature of 200C. find the free expansion of the rod when the temperature is raised to 65 0 C. Find the temperature stress produced
You need to compare measured and predicted deflections for the three situations described below. Comment on reasons for the differences between the predicted and measured values. Recall that E = 69 GN/m2, rho = 2700 kg/m3, and the beam cross-section ..
A moist soil sample wights 346g.After drying at 105 degree celsius it then wights 284g. the specific gravity of the mass and of the soil is 1.86 and 2.70.
As a design engineer you are responsible for all the drawing documentation from your organisation. What are the key aspects of the drawing you need to check before sending it to the construction division
At an excitation frequency of 4 Hz, the response tends to increase without bound(ie a resonant condition). Next, a weight of deltaW= 5lb is attached to the mass m and the resonance test is repeated.
compute the critical buckling load for a 2.5m timber column of full size square section 0.10m x 0.10m. The column has pinned ends(k=1). Assume the modulus of elasticity is 12Gpa and that the Euler formula applies
A quartzite sample in a compression testing machine is 180mm long and 54mm in diameter. what is the stress under a load of 100kN? if the modulus of elasticity is 102kN/mm2, find the strain develope in the sample.

The center to center spacing to the two tanks is 14 m. The new tank imparts 150 kPa at the ground surface. Find the increase in vertical stresses due to the weight of the two tanks mid- way between the two tanks at the center of the clay layer.
Plot a graph showing the discarge per unit width per unit width q for various depths if the specific energy remains constant at this value. What will be the depth when the discharge is 1/3 of the discharge at critical depth
Pressure Variation in a Fluid at Rest 1. In April 2010, the Deepwater Horizon drilling rig experienced a severe explosion and fire and sank off the coast of Louisiana. Eleven persons died, and 17 others were injured. The resulting uncontrolled oil re..
In New york you had a balloon inflated with helium (He) and you measured its temperature, which was 89.6 degree F, and its pressure, which was 100,000 N/m^2. In Colorado, however, you noticed that the temperature of the He was 69.8 degree F and th..
