Please be clear in explanation!

1. Define density, mass, weight, and specific gravity. A room is 4m wide, 5m long, and 3m high. Air pressure in the room is 110 KPa absolute and the temperature is 27C. Assuming ideal gas behaviour, determine the mass, density, and specific gravity of the air using water as reference density. (The density of water is 1000kgm-3, the molar mass of air is 29g/mol, and R=8.314 J/(kg mol)).

Let the minimum fresh air requirement for the room be 9.0 Air Change Rate per hour. That is, the complete air filling the room is completely changed 9.0 times in one hour. If the ventilation requirement is met entirely by a fan calculate the volume flow rate per hour (m3/hour) required. Determine the flow capacity of the fan in m3/s. Determine the fan casing diameter if the velocity is not to exceed 6 m/s.
