LAB #13 FLUIDS
Lab 13: Fluids:Buoyancy Potpourri • GOAL(S): PART 1: • TO DETERMINE THE S.G. OF 2 DIFFERENT METALS BY APPLYING PRINCIPLES OF BUOYANCY
BACKGROUND/SKETCH: STEP 1 STEP 2 T Fb T Wmetal W metal
VH2O = Vmetal W = mg Fbuoy= rgV rmetalgV W = SG rH2OgV = Fb
Lab 13: Fluids:Buoyancy Potpourri • GOAL(S): PART 2: • DETERMINE THE MASS OF A BLOCK OF WOOD
Part 2: Float Your Boat WATER LINE: (BLOCK PARTIALLY SUBMERGED) Fb Fb = mg H mg h W L Fb = Weight of water displaced VOLUME OF H2O DISPLACED = VOLUME OF BLOCK SUBMERGED
Lab 13:Fluids:Buoyancy Potpourri • GOAL(S): PART 3: • TO DETERMINE THE DENSITY OF He GAS
WHe Wm Part 3: r of He Fb W balloon Fbuoy = Wm + WHe + Wballoon m WHe = Fbuoy - Wm - Wballoon Fbuoy = rair gV WHe = rHe gV
Given Values (r He ACCEPTED = .18 kg/m^3) (r air ACCEPTED = 1.29 kg/m^3) V balloon = 12.6 LITERS 1 MOLE OF GAS @ S.T.P. = 22.4 LITERS MASS OF BALLOON = 9.215 g
