nozzle

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe.
A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In a nozzle, the velocity of fluid increases at the expense of its pressure energy.

    Ive just landed a job installing an oil tank to provide supply to a Camray Boulter 5 Combi and in the MI (Because I will have to service the boiler as well) it mentions nozzle sizes of 0.85 x 60°W but I can't find any. Does anyone know where I can get one, or what the equivalent might be?

    I'm struggling with my R.B.L G5BF 50/70 burner. I have got plenty of oil from the pressure port of the pump (brand new last year) but nothing from the outlet to the nozzle, passed the stem valve. There is no magnetism from the coil when you wave a screwdriver near it. So, I've changed the...

    Red diesel

    Is there a rule of thumb when converting to red diesel? Farmer custard of mine just bought a used warm air blower for the truck she'd buy wants to run it on diesel. I think it's an increase in pump pressure and bigger nozzle but by how much and what am I looking for on FGA? Thanks
