Question

Task 20: We are considering a 50 cm by 60 cm hexane pool fire in this task. a) Calculate the mass loss rate from the fire. b) Calculate the energy production from the fire. c) Calculate the flame height of the fire. d) Calculate the smoke production from the fire at 3m and 5 m e) Explain the result in d). Task 21: What is a design fire, and why is it important? Task 22: There is a silo, 30 m high, with one opening at the top and one at the bottom. Both openings are 200 cm wide and 60 cm high. Calculate the mass flow through these openings when there is 45°C inside the silo and 10°C outside.

Step 1

50 m × 0.60 m = 0.30 m²) Assumptions and constants used - Representative hydrocarbon pool burning rate (mass flux) m″ ≈ 0.07 kg·m⁻²·s⁻¹ (typical for small hydrocarbon pool fires). - Lower heating value (LHV) hexane ≈ 44 MJ·kg⁻¹. - Heskestad flame-height Show more…
