Heаt exchаngers оften cоnsist оf mаny triangular passages. Consider the triangular duct shown in the figure with: L=62.0 cm a=2.0 cm, β=80 deg L = 52.0 text{cm}, qquad a = 2.0 text{cm}, qquad beta = 80^circ The average fluid velocity is V=2.0 m/sV = 2.0 text{m/s} The fluid is SAE 10 oil at 20∘C20^circtext{C}, with properties ρ=870 kg/m3,μ=0.104 kg/(m.s)rho = 870 text{kg/m}^3, qquad mu = 0.104 text{kg/(mcdot s)} Estimate the pressure drop ΔpDelta p in Pa through the triangular passage.
