A rigid tank A of volume 0.6 m3 contains 3 kg of water at 120?C, and rigid tank B has a volume of 0.4 m3 with water at 600 kPa, 200?C. The tanks are connected to a piston/cylinder initially empty with closed valves as shown in Fig. P3.217. The pressure in the cylinder should be 800 kPa to float the piston. Now the valves are slowly opened and heat is transferred so that the water reaches a uniform state at 250?C with the valves open. Find the final volume and pressure, and the work and heat transfer in the process.
During field operations for traverse ABCDEF, some measurements for courses CD and DE were omit-ted due to obstacles. Calculate the missing length and azimuth.
The concrete cylinder 6 in x 12 in broke incompression at a load of 110000 lbs. Compute the crushing strength of concrete. Estimate the tensile strength and the modulus ofelasticity.
On a very hot day, I saw a 1.6 meter long steel bar held between two rigid supports that had buckled due to the heat. The bar had a cross section of 10 mm by 40 mm, and I assume was A36 steel.
Determine the side slopes (i.e. 1:3, etc.) of a suppressed (n=0) trapezoidal sharp crested weir with width B and upstream head H so that the discharge through it is the same as that through a rectangular sharp crested weir
An undisturbed soil sample has a total unit weight of 19.4 kN/m3, a dry unit weight of 16.9 kN/m3, and a specific gravity of soil solids (Gs) of 2.69. If the sample could be saturated without changing its porosity, calculate the amount of water (i..
The pinion is made from AISI 1040 WQT 800. The gear is made from gray cast iron, ASTM A48-83. class 30. Design for 15 000 hr life.
An automobile modeled as a single-degree-of-freedom system free to vibrate in the vertical direction. In a free vibration test the amplitude of oscillation is observed to decrease from 20mm to 2 mm in one cycle which takes 3 seconds.
An elbow, 90 degrees smooth bend flanged, is used in the Alaskan pipeline. Inside pipe diameter is 48 inches. Flow is 1.6 million barrels a day. 1 barrel=42 gal. Velocity is 8.27 ft/s. SG=0.93
Plot the ground level concentration of sulfur dioxide as a function of distance from the stack and determine the maximum ground level concentration at both with and without air pollution control and the distance from the stack where the maximum co..
Water flows steadily through a horizontal 30 degree upward bend. The inlet diameter is 0.3 m, the velocity is 12 m/s, and the pressure is 128 kpa gage. The outlet diameter is 0.38 m and the pressure is 145 kpa gage.
What would be the absolute pressure, P in kPa, of carbon dioxiode at 20 degrees celcious if the specific weight of carbon dioxide at 20 degrees celcious is 18 N/m^3 and the gas constant, R =1.889x10^2 J/kg*K.
A pipeline 1200 ft long and 8 in. in diameter has at its inlet point 75ft of available hydraulic energy with respect to the reference level. The velocity in the pipe is 5 fps: the pressure at its end is 12psi.
