of the fluid can be In a reactor (3D, cartesian). suppose the pressure and tem expressed using the following equation: P=0.052? + 0.2in(y) +0.0123 (1) unit: x,y,z[m], Platm) T = 298.15 +1.2ln(x) + 0.1542 + z. (2) unit: x,y,z[m], T[K] And it's also known the density of the fluid can be treated as a constant: 0.8g/ml, the veclosity of the fluid can be expressed as (unit: m/s): u = 8(0.02x2 +0.03y) +,(0.0458 +0.21ny) +33(0.084 +0.05 * 2?) (3) unit: x,y,z[m], um/s) 1. Calculate: P and T at point (4.5,5.2.2.7) (unitm) . VP and VT . VP and VT at point (4.5,5.2 2.7] (unitum) 2. Calculate the momentum density and divergence of momentum density 3. Calculate the momentum density and its divergence at point (4.5,5.2.2.7) (unit:m) (hint: pay attention to the units)
