A double bubble tube is being used

in the measurement of process

density. The transmitter used is

configured for a span of $50cm$ of

water pressure.

a$.$ Calculate the range of specific

gravities measurable with this

system.

b$.$ Calculate the upper range

value $($URV$)$ required in $cm$

$H2O$ if the transmitter's output

is $6mA$ when the process

liquid's specific gravity is $1\mathrm{.}5.$

$3$a$.,1\mathrm{.}488$ to $1\mathrm{.}586$

$3$b$.,758\mathrm{.}75cm$
