Question

An inviscid flow field has a potential function of$ = 2 x° y? + 4 in units of m2 /s and with x and yin meters. Consider the points (xo=1,

yo=1) and ,(x1=1.2, y1=1.7), where units are in meters. Assume water(y = 9800 N/m³) and g=9.8 m/s².What is the fluid speed (i.e., magnitude in m/s) at (wo=1, yo=1)?
