This document provides tutorial questions for a ventilation design class. It asks students to use three different duct sizing methods - equal velocity, velocity reduction, and equal friction - to calculate the duct and fan sizes for a ventilation system based on the air flow rate and selected air velocities. It also asks students to determine the appropriate air changes per hour for a recording studio.

BS2 Tutorial 2 ventilation design
- 1. BACHELOR OF QUANTITY SURVEYING (Honours) BUILDING | SERVICES | TWO (BLD60503) August 2016 Semester Tutorial 2 – Ventilation design Q1 Using Equal velocity method, find the size of duct A & B and fan rating. Selected air velocity throughout the system (duct A & B) is 5m/s Given Q, the quantity of air is equally extracted through each grille. Q = Room volume x air changes per hour
- 2. Q2 Using the velocity reduction method, find duct size A & B and fan rating. Given selected air velocity in ductA = 5m/s and duct B = 3 m/s Q3 Using equal friction method, find the size of ductA & B and fan rating. Selected air velocity through duct A = 5 m/s If the room is a recording studio, find the air changes per hour.
