Webb9 apr. 2024 · Problem 1: Calculate the mass flow rate of a given fluid whose density is 700 kg/m3, velocity, and area of cross-section is 40 m/s and 30 cm2 respectively. Solution: As per given data ρ = 700 kg/m3 V = 40 m/s and A = 30 cm2 = 0.30 m2 The formula for calculating mass flow rate (m) m = ρVA m = 700 × 40 × 0.30 m = 8400 kg/s Webb13 mars 2015 · The PEA with the lowest molecular weight (Mw close to 8000 g/mol) was the most appropriate to obtain electrospun samples with a circular cross-section since higher molecular sized polymers show solvent retention problems derived from the high viscosity of the electrospun solution that rendered ribbon-like morphologies after the …
