A horizontal venturimeter with inlet diameter $200mm$ and throat diameter $100mm$ shows a deflection in manometer reading of $180mm$ of $Hg($connected between upstream end and the throat$),$ when water flows through the venturimeter. For $C{l}_V=0\mathrm{.}98,$ calculate the flow rate $($in $m^3{s}^{-1},$ round off to two decimal places$).$

Assume ${}_{\text{m}\text{a}\text{n}\text{o}\text{m}\text{e}\text{t}\text{r}\text{i}\text{c}\text{f}\text{l}\text{u}\text{i}\text{d}}=13600\frac{kg}{m^2},{}_{\text{f}\text{l}\text{o}\text{w}\text{i}\text{n}\text{g}\text{f}\text{l}\text{u}\text{i}\text{d}\frac{?}{?}\text{w}\text{a}\text{t}\text{e}\text{r}}=1000\frac{kg}{m^2}$

Flowrate of water from a centrifugal pump is $230m^3*h^{-1}.$ If the inner diameter of suction line is $0\mathrm{.}128m,$ pressure head at the suction end of the pump is $7\mathrm{.}98m,$ and the vapor pressure of water at the temperature of the fluid is $4\mathrm{.}25$kPa, the NPSH $($available$)$ would be in meter $($round off to one decimal place$).$

Identify the wrong statement with regard to the fluidization

a$)$ At the point of incipient fluidization, the particles acquire terminal velocity

b$)$ Beyond incipient fluidization, if the fluid velocity is increased further, the pressure drop does not increase proportionally

c$)$ Beyond incipient fluidization, the bed height changes

d$)$ At the point of incipient fluidization, the pressure force supports the buoyancy corrected weight of particles

In a sand bed type water filter, the water is stored immediately above the sand pack. The height of the sand pack is $2m,$ and the diameter is $1m.$ If the permeability of sand pack is $1$ Darcy, calculate the magnitude of flow rate $($in lit$/$hr$)$ at the bottom of the sand pack.

$K(1$ Darcy$)=9\mathrm{.}869{10}^{-13}$
