The design conditions for an air-conditioned hall is 

Inside condition 24°C DBT and 60% RH 

Outside condition 38°C DBT and 28°C WBT 

Sensible heat gain 167040 kJ/hr 

Latent heat gain 41760kJ/hr 

Infiltrated air 20CMM 

Coil ADP 10°C 60% of total air is recirculated and mixed with conditioned air after cooling coil.

Determine i) The condition of air before entering the hall ii) The condition of air leaving the conditioner coil iii) BPF of cooling coil iv) refrigeration load on cooling coil.

For hot and dry weather conditions show the arrangement of summer air-conditioning system and represent the processes on psychometric chart.

A beam ABC with an overhang at one end

supports a uniform load of intensity 12 kN/m and a

concentrated moment of magnitude 3 kN . m at C

(see figure).

Draw the shear-force and bending-moment

diagrams for this beam.
