i dunno what normal peeps think about when they stand* near their kettle on the cooktop, waiting for it to boil, but here's wot this dunderheaded dropbear just thought
me kettle has an ~3mm diameter hole in the centre of the spring-closed spout cover, thru which the steam emits at some pressure as boiling point approaches, then arrives. the diameter & thickness forms an orifice, in fluid-mechanics terms. thus the frequency of the banshee screech depends in part on the diameter [coz Q = V*A, & V directly relates to the generated f], given a fairly typical range of normal water density, purity, enthalpy, elevational atmospheric pressure et al
so, the pondering went, did the peeps wot designed n made this stainless steel curvaceous kettle apply ridgy didge fluid-mechanics calculations to ascertain the necessary orifice diameter, for peak banshee? 🤔
or did they just say "nah, fuck that, let's drill a series of different hole dias in a series of spout covers in the workshop, to arrive entirely heuristically at a good size to achieve peak banshee"? 🤷
anyway, the screaming ensued, i have me mugga, so piss orf n let me sip it in peace, wouldya? 🤪
*will anyone have a go at me for standing on my cooktop, & suggest i might just stand on the floor?
