The flow rate required to yield a specified reading on an orifice meter varies inversely as the square root of the fluid density; that is, if a fluid with density 1(g/cm3)\rho_{1}\left(\mathrm{g} / \mathrm{cm}^{3}\right)1(g/cm3) flowing at a rate V1(cm3/s)\dot{V}_{1}\left(\mathrm{cm}^{3} / \mathrm{s}\right)V1(cm3/s) yields a meter reading \phi, then the flow rate of a fluid with density 2\rho_{2}2 required to yield the same reading is V2=V1(1/2)1/2\dot{V}_{2}=\dot{V}_{1}\left(\rho_{1} / \rho_{2}\right)^{1 / 2}V2=V1(1/2)1/2 a) An orifice meter has been calibrated with nitrogen at 25C25^{\circ} \mathrm{C}25C and 758 mm Hg, but it now has methane flowing through it at 50C50^{\circ} \mathrm{C}50C and 1800 mm Hg. 9th Grade Biology Resources 7th Grade Science 9th Grade Biology Resources Debate Research Packet: File Size: 72 kb: File Type: docx: Download File. 1 RRWW : 2 RRWw : 1 RRww : 2 RrWW : 4 RrWw : 2 RrWw : 1 rrWW : 2 rrWw : 1 rrww, If a mother has type O blood and the father has type AB blood, what type of blood would the baby most likely have?
