Butane gas of density = 2.5567 kg/m^3 flows at speed v1 in a horizontal pipe with cross sectional area A1 = 0.0475 m^2 which widens to a larger still horizontal section of area A2 = 0.0665 m^2 in which it flows at speed v2. If the pressure difference between the two sections is measured accurately to be p2-p1 = 276.1236 Pa, Find (a) speed v1, and (b) the volume flow rate of the gas.
