WebThe fouling rate for the wired probe, 8.7 × 10 −10 m 2 K W −1, was noticeably lower even at a higher surface temperature than that on the plain probe (3.0 × 10 −9 m 2 K W −1 ). The reduction in fouling rate is almost certainly due also to the increased surface shear stress when wires were fitted. Sign in to download full-size image Figure 3.21. WebJul 22, 2024 · Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. Q = (999.78kg/m3 x 0.0995m3/s) x 4.19kJ/kg/K x ( (12*c+273.15K) – (6*c+273.15K)) We add 273.15K to the celcius to convert it to units of Kelvin.
