If that's the case, does anyone know how to calculate air velocity in a duct from the volume of air a fan can move and it's static pressure? Including resistance from friction and bends in the duct.
Errr....Simple.....Find someone who wears an Irish. Ask said person to apply the Irish without glue. Stand him/her in front of a fan. Put the speed on low and observe. Calculate the air velocity by measuring the time and the distance the Irish lands in millimetres. So if its 50 seconds by 1k millimetres the air velocity is 20....Dooahh... I thought everyone knew that.

Do you know anyone who wears an Irish?

I don't but wish I did.

If you do know someone maybe I could meet them and become their friend.

Would this still hold true if the person's wearing a syrup instead of an Irish?
 
Please excuse a diversion. Found myself watching Love your Garden with Titchmarch this morning. A triple amputee Marine with 3 children. He'd stood on and IED in Afghanistan. They made an amazing garden for him. He'd raised over 250k for forces charities running across America on those blade things and hand cycling across the UK. It just strikes me that as a nation we miss the opportunity to really support those that need massive help...
 
The fact is that many systems of insulation were considered safe in the last few years, have proved to be dangerious. This cladding was not apparently installed illegally, it was installed without regard to the danger.
In the case of Grenfell Tower, the problem was the combination the cladding, power surges, lack of sprinklers and inadequate safety advice all contributed to the numbers of lives lost.

It seems to me that the system for testing the individual components was not adequate and that is a failing of government at national and local levels as well as the companies that developed and supplied these panels.

Who will end up being blamed, my bet is no one individual. No one organisation and no corporate body.

The conclusion will be that this was a tragic set of circumstances that no one could have predicted.... except they did!
 
HRI tower block fire safety – latest position

Chris Long, Chief Executive of Hull and East Yorkshire Hospitals NHS Trust says:

“The safety of everyone using the hospital is of utmost importance to us.

“In a bid to provide assurance for our patients, staff and visitors, and in accordance with guidance set out by NHS Improvement, cladding samples have been sent away for testing.

“Based on the information obtained to date, we can confirm that the cladding on the Hull Royal Infirmary tower block is not the same as that used on the Grenfell tower block.”
