Calculations for total bore-resistance as [CO.sub.2] is cooled and condensed was determined by entering single phase properties of [CO.sub.2] at state 4 into a commercially available software package that takes into account bore-hole geometry and fluid properties.
When coupled with GSE system, bore-hole lengths can be significantly reduced and sized to balance with the building hot water needs.
* SIR - Does the decision by Severn Trent to sell 30 million litres of bore-hole water a day to drought-hit England mean Wales will be denied potentially increased revenues for Dwr Cymru and reduced bills for consumers?
THERE WERE 50,000 illegal bore-holes in Cyprus said a water board official yesterday, as he tried to explain why a spring in Farmakas village, which had been running for as long as people remembered, was drying out.
Last year, a group of Australian researchers reported something different in the data coming from three strain-sensing instruments they had installed near Parkfield The instruments lie in bore-holes and are designed to sense forces within the crust that gently deform the originally circular holes.
