Chemical Heat Transfer

A chemical engineering experiment was run to study heat transfer in a shallow  fluidized bed.
Data were collected on the following four candidate regressors -
X1:  fluidizing gas  flow rate in pounds per hour,
X2: supernatant gas  flow rate in pounds per hour,
X3: supernatant gas inlet nozzle opening in millimeters,
X4: supernatant gas inlet temperature, oF.

The measured responses are
Y1: heat transfer coefficient,
Y2: thermal effciency.
Twenty observations were gathered with the data attached in a csv file

Objectives:  Prediction of Y1, Y2
