An oil of 0.87 specific gravity and 6 centipoises viscosity flows through a pipeline. An orifice with opening diameter of one-half of the inside pipe diameter is used to measure the flow. It is proposed to replace this orifice with a venturi with throat diameter equal to the orifice diameter. If the coefficient of the orifice is 0.61 and that of venturi 0.98 and the flow rate is unchanged calculate: (a) The ratio of the venturi reading to the orifice reading (b) The ratio of the net pressure loss due to the venturi installations to that found with the orifice
