Assume an inviscid, incompressible flow. Also, standard sea level density and pressure are 1.23 kg/m3 (0.002377 slug/ft3) and 1.01 × 105 N/m2 (2116 lb/ft2), respectively. Derive the velocity potential for a doublet.

Q#1: What is stream wise acceleration? How does it differ from normal acceleration? Can a fluid particle accelerate in steady flow? Express the Bernoulli equation in three different ways using (a) energies, (b) pressures, and  (c) heads.

SAE 50W oil at 20 °C flows from one tank to anotherthrough a tube 160 cm long and 5 cm in diameter. Estimatethe flow rate in m3/hr if z1 = 2 m and z2= 0.8 m.

Air at 20⁰c and 1 ATM flows over a flat plate, v= 35 m/s. The plate is 75 cm long and guarded at 60⁰c. Suppose the depth of one Units on Z, count the transfer of Calor from that plate.
