= Air has a gas constant of R = 287 [J/(kg C)]. At standard temperature 15°C and pressure, air has a dynamic viscosity of, μ 0.0000179 [kg/(m·s)] and a density of p = 1.23 [kg/m³]. If a circular pipe is to carry Q = 0.079 [m³/s] of air at standard atmospheric pressure, find the following assuming that Re < 2100 gives laminar flow: Part 1. If the flow must remain laminar, what is the minimum diameter of the pipe? 19 5% 95% Submit Part 2. What would be the density of air at 80.9 [C]? [m] 33 3% 100% Submit [kg/m³]

Quantity takeoffs (QTO) are precise estimates of the materials and labor costs required to finish a construction project. During the pre-construction phase, an estimator prepares them, breaking down the project into smaller, more manageable parts that ar…
