The velocity of a fluid stream can be measured with fairlyaccurately by measurin

Question

The velocity of a fluid stream can be measured with fairlyaccurately by measuring the total dynamic pressure inthe flow. The velocity is then
U = [(2*(P_flow - P_atm))/]^0.5
The gage pressure, (P_flow - P_atm) is measuredusing an electronic pressure transducer. The pressure transducer has a calibration such that
(P_flow - P_atm) = 113V_out
If Vout = 2.2 V and the uncertainty in the measurement ofV_out is 0.236 V, what is the resulting uncertainty inthe velocity, U, in m/s? Assume that = 1.2kg/m3 with an uncertainty of 0.139 kg/m^3.
