answer:To determine the specification of the heater, we first need to calculate the heat transfer area and power required for vaporization. 1. Calculate the heat transfer area (A) using the formula A = π * d * L, where d is the difference between the outer and inner diameter, and L is the length of the cylinder. A = π * (52 mm - 50 mm) * 350 mm = 3.1416 * 2 mm * 350 mm = 2199.11 mm² 2. Calculate the heat transfer rate (Q) required to vaporize the Jet A fuel completely. To do this, we need to know the following: - Specific heat (Cp) of Jet A fuel - estimated at 2100 J/kg*K - Latent heat of vaporization (Lv) - estimated at 280 * 10^3 J/kg - Temperature difference (ΔT) - assuming a room temperature of 20°C and a vaporization temperature of 180°C, ΔT would be 160°C - Density (ρ) of Jet A fuel - estimated at 0.8 kg/L 3. Calculate the mass flow rate (m_dot) using the formula: m_dot = flow rate × density m_dot = 0.31696 L/min × (1/1000 m³/L) × 60 min/h × 0.8 kg/L = 0.0151 kg/h 4. Calculate the power required to heat the fuel to vaporization temperature (P_heating) using the formula: P_heating = m_dot × Cp × ΔT P_heating = 0.0151 kg/h × 2100 J/kg*K × 160 K = 5000.5 J/h 5. Calculate the power required to vaporize the fuel completely (P_vaporization) using the formula: P_vaporization = m_dot × Lv P_vaporization = 0.0151 kg/h × 280 * 10^3 J/kg = 4217.45 J/h 6. Calculate the total power required (P_total) as the sum of P_heating and P_vaporization. P_total = 5000.5 J/h + 4217.45 J/h = 9217.95 J/h 7. Convert P_total to Watts (W) using the formula: 1 J/h = (1/3600) W P_total = 9217.95 J/h × (1/3600) W = 2.56 W Based on the calculations, the heater should have a heat transfer area of 2199.11 mm² and a power rating of approximately 2.56 W to vaporize Jet A fuel at a flow rate of 0.31696 L/min.

answer:Based on the given requirements, you would likely need a tubular or cartridge heater. Tubular heaters are versatile, efficient, and suitable for direct immersion in liquids. They are commonly used in fuel/oil tanks, water systems, and other applications requiring direct heating. The heater should have the following specifications: - Heat transfer area: 2199.11 mm² - Power rating: Approximately 2.56 W The necessary dimensions for the heater can be determined using the required heat transfer area and the surface area formula for a cylinder (A = 2πrL, where r is the radius and L is the length). First, we convert the required heat transfer area to square meters: A = 2199.11 mm² × (1/1000)² = 0.00219911 m² Let's assume the heater is cylindrical, with a radius (r) and length (L). Rearrange the surface area formula to solve for the length (L): L = A / (2πr) Now, we need to choose a suitable diameter for the heater. Typical cartridge heaters have diameters of 6.35 mm (1/4 inch) to 31.7 mm (1.25 inches). Tubular heaters typically start at 5.33 mm (0.21 inches). The heater's diameter will depend on various factors, such as available space for installation, heat distribution, and heater material. For illustration purposes, let's choose a 6.35 mm diameter for the heater (a common size for a small cartridge heater). Calculate the radius: r = diameter/2 = 6.35 mm / 2 = 3.175 mm = 0.003175 m Now, we can calculate the required length (L) of the heater: L = A / (2πr) = 0.00219911 m² / (2π × 0.003175 m) ≈ 0.11011 m So, a suitable heater would be a 6.35 mm diameter cartridge or tubular heater with a length of approximately 110.11 mm. Keep in mind that these dimensions are a rough estimate based on general requirements. The final dimensions can vary depending on specific application constraints and the chosen heater type.
