Webb13 maj 2024 · Across the exit area we may encounter an additional force term equal to the exit area Ae times the exit pressure minus the free stream pressure. The general thrust equation is then given by: F = (m dot * V)e - (m dot * V)0 + (pe - p0) * Ae. Normally, the magnitude of the pressure-area term is small relative to the m dot-V terms. WebbCritical thickness of insulation for a pipe can be calculated by formula r cr = k/h. r cr = 0.6/60 = 0.01 m. Hence r cr > r 1 and heat transfer will increase with the addition of insulation up to a thickness of r cr – r 1 = (0.020 – 0.005)m = 0.015 m.
