ReciprocatingChiller question

[bwd111]

10902Been racking my brain on these questions

1. Approach temp=
2.cooler flow rate=gpm
3 RISE
4. COOLER PRESSURE DROP = PSI


Also what will the net refrigeration effect be if there is a fouling factor of 0.0025

Recommend re-phrasing the question!

How would I re-phrase question

I forgot to add diagram. Sorry for ther confusion! My mistake

approach refers to SST versus water entering chiller.
Cooler flow rate in US gallons per minute, governs the total performance on system.
Rise refers in general to the temp change in water flowing through chiller.
Cooler pressure drop or delta P, is a double check on water flow rate, as chiller manufacture would has publish data on flow rates at given pressure drops.
Fouling factor is the maximum allowable fouling effect on chiller tubes, even closed circuit chilled water systems gunge up, this effects the heat transfer and reduces chiller capacity.

For rise I came up with 11 degrees
for app0roach i came up with 15 degrees
cooler flow rate came up with 110.7 gpm
fouling factor came up with 48 tons

Was anybody close to my answers

using figures off drawing and stated water flow rate at 110.7 USgpm, converted to SI, I get 178.62 Kw NRE ( net/ nominal refrigeration effect ) or 50.78 tons

OK SI metric system,,, Q (water) = L/sec x Delta TK' x specific heat 4.192 kj/kg = Kw refrig

Cannot remember specific heat value of water in imperial.

how close were you to this answer I had cooler flow rate came up with 110.7 gpm
