2. Hemispherical endcaps are welded to the cylindrical main body to form a propane storage tank. The outside diameter is do = 4 ft and the length of the cylindrical section is Lc=5 ft. If the maximum internal pressure is not to exceed 3200 psi and the material has an allowable stress σallow = 24 ksi, determine the minimum required wall thickness. (Solution: t = 2.824 in) do

The propane gas tank has an inner diameter of 2500 mm and wall thickness of 18 mm. If the tank is pressurized to 5 MPa, determine the absolute maximum shear stress in the wall of the tank

A spruce tree is 20 m tall with a trunk diameter of 0.4 m. Its needles have a measured water potential of –2.5 MPa, while the roots have a measured water potential of –1.2 MPa. Hydraulic conductivity through the stems is 7×10–8m3s/kg. What is the transpiration rate of the tree (in g H2O/s), assuming that 1.5% of the stem cross sectional area contains water-conducting vessels?   Hints: 1 MPa = 106kg/(m·s2); water density = 1 g/cm3 Start by using the flow equation (p. 104 CMV textbook) to calculate the rate of water movement in m s-1 Multiply the rate by the cross-sectional area of water-conducting vessels

c) Tlhe specific gravity of a liquid is 0.75. What height of that liquid is needed to provide a pressure difference of 200 kPa?

5. A 15.0-cm long cylinder has a moveable piston with radius 2.00 cm. (a) what is the volume of the cylinder (in m³)? (b) if the initial air pressure is 101 kPa at 0.0 °C (STP), what is the air pressure inside the cylinder when it is pushed down 4.00 cm (to 11 cm long)? (c) If the air temperature inside the compressed cylinder is heated to 20.0 °C, what is the new air pressure?

1. A bicycle pump inflates a tire of volume 565 mL until the gauge pressure is 6.47 bar at a temperature of 21.7°C. (Note: the volume of the tire before and after it is "inflated" is 565 mL. Initially, the tire contains air at ambient atmospheric pressure.) (a) If the barometric pressure is 1.01 bar, what is the absolute pressure in the tire? (b) (c) How many moles of air does the tire contain? What volume of air at 1.01 bar and 21.7°C did the pump transfer?

600 lb ! A 600-lb tensile load is applied to a test coupon made from 1-in. flat steel plate (E = 29 X 10° psi, p = 0.30). Determine the result- ing change (a) in the 2-in. gage length, (b) in the width of portion AB of the test coupon, (c) in the thickness of portion AB, (d) in the cross-sectional area of portion AB. 2 in. -600 lb A B F
