Water flow for the condenser to do what?

You give no usable information.

At this point all that could be said is look at the pump specification.

Rule of thumb: GPM = 3 x TR. In your case 45 GPM.

The undefined "we" will also have had a Manual that was supplied with it. One could have opened the Manual and looked it up, so calculation would not have been necessary. In addition, one could have phoned the equipment manufacturer and asked, so calculation would not have been necessary. One could have also looked in the Commissioning Records for the equipment and observed the figure that it had been set to at the time it was orignally placed in service, so calculation would not have been necessary.

In the absence of any of these, any WAG would do.

Use this formula

Q = m x Cp x ∆t;

Where;

Q = Heat load to be dissipated (KW)

M = mass flow of water required for cooling (kg/sec)

Cp = Specific heat capacity of cooling liquid (KJ/kg °C)

∆t = Difference in temp. i.e. outlet - inlet (°C)
