Front of calculator includes scales for friction, velocity,\nround duct size, weight per linear foot of round duct, surface area in square\nfeet per lineal foot of round duct, rectangular equivalents of round duct\nsizes, weight per linear foot of rectangular duct and surface area in square\nfeet per linear foot of Rectangular duct. Back of calculator has equivalent\nfeet of straight duct for commonly used fittings, corrected pressure drop\nchart, and many HVAC formulas. Pull out slide has recommended duct velocities,\nrecommended gauges for sheet metal, and much more. The photo shows front side\nof the tool. This slide is made of thick durable water resistant paper stock\nwith glued edges and corner rivets. Tool measures 4 inches high and 8.5 inches\nwide.
