Question:A glass container without a lid with equal dimensions, each 19 cm long. If the glass of the container is 0.5 cm thick, Find the volume of the glass which the container is made from. Help it's mathematics homework! it's a cube... and how you just solved it is really complicated ... it's 3rd grade math!

Answers:There is 2 way to find the volume, one is the mathematic formula and the other one is D=m/v. I think you hmwk wants the Math formula which is Lx WxH. find the length the width and the height and multiply them all. and there's your answer.

Question:How do I calculate the total volume of air breathed in and out per minute when the tidal volume is 2.75 and breathing rate is 27.5? Thanks

Answers:2.75 L X 27.5= 75.625 L

Question:I tried doing this problem using factor label conversion and got it wrong (I got 61.2L). Maybe someone here can help me, the problem is: Calculate the volume of O2 (at STP) required for the complete combustion of 4.62 L of acetylene (C2H2) at STP. Here is the formula: 2 C2H2(g) + 5 O2 = 4 CO2 + 2 H2O(l) How do we know what the temperature is?

Answers:Volume O2 needed = 4.62 x 5 /2 = 11.6 L

Question:6.35 L sample of monoxide is collected at 55 C and .892 atm. What Volume will the gas occupy at 1.05 atm and 20.0 C Any explanation of how to solve and the answer will help please :D

Answers:Use P1V1/T1 = P2V2/T2 P1 = 0.892at V1 6.35L T1 = 55+273=328K [temp must be in kelvin [asolute] P2 = 1.05at V2 = ? = answer T2 = 273 +20 =293K Enter data in Gas Law formula above and solve for V2

tidal hydro turbine CFD :Vertical axis hydro turbine is working beneath the tidal bridge. Its rotor bay section is about 10X10 m^2. The flow is driven only by the pressure gradient which is created by the head difference between upstream and downstream crosswise the bridge. All about 8.5 million mesh elements are created with Hexahedral other than Tetrahedral. Two phase flow model is applied for the air and sea water. Turbulence model is k-epsilon. Sliding mesh is used. The color on the turbine shows the distribution of pressure. The free surface is the contour of 50% volume fraction of the sea water. The color on the free surface is the variation of the velocity of the sea water. Also, the torque and the power output are calculated for each time step. The video shows the transient progression which lasts about 50 seconds.
