Force = mass * acceleration force = pressure * area what is the formula for pressure? pressure = (force) / (area) pressure = weight / area pressure = gamma * height what is specific gravity? Specific gravity is the ratio of the density of a substance compared to the density (mass of the same unit volume) of a reference substance. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance. The reference substance is nearly always water for liquids or air for gases what is the specific gravity formula for hydraulic oil? SG = γ of oil  /  γ of water What is the specific weight of water? SG H2O = 62.4 lb/ft3 SG H2O = 9800 N/m3 what is "rho"? Density what is the formula for density? ρ = mass / velocity ρ = gamma / gravity what is the value of atmospheric pressure? 14.7 psia 0 psig what is "mu"? μ = viscosity. μ abs = absolute (dynamic) viscosity what is the unit for absolute (dynamic) viscosity? μ = pascal-second (Pa·s) (equivalent to N·s/m2, or kg/(m·s)) .remove_background_ad { border: 1px solid #555555; padding: .75em; margin: .75em; background-color: #e7e7e7; } .rmbg_image { max-height: 80px; } Authorsanjer ID215574 Card SetEET 293 - Hydraulics and Pneumatics DescriptionEET 293 - Hydraulics and Pneumatics Updated2013-04-24T21:48:18Z Show Answers
