Calculate the angle of banking on a bend of 100m radius so that vehicles can travel round the bend at 50km/hr without side thrus

saw5 [17]

Answer:

11.125°

Explanation:

Given:

Radius of bend, R = 100 m

Speed around the bend = 50 Km/hr = $\frac{5}{18}\times50$ = 13.89 m/s

Now,

We have the relation

$\tan\theta=\frac{v^2}{gR}$

where,

θ = angle of banking

g is the acceleration due to gravity

on substituting the respective values, we get

$\tan\theta=\frac{13.89^2}{9.81\times100}$

or

$\tan\theta=0.1966$

or

θ = 11.125°

A nanometer connected to a pipe indicates a negative gauge pressure of 70mm of mercury .what is the pressure in the pipe in N/m^

prohojiy [21]

Based on the calculations, the absolute pressure in the pipe is equal to 90,670.4‬ N/m².

<h3>How to calculate the absolute pressure?</h3>

Mathematically, absolute pressure can be calculated by using this formula:

$P_{abs} = P_{atm} + P_{guage}$

<u>Scientific data:</u>

Atmospheric pressure (Patm) = 1 bar = 1 × 10⁵ N/m²

Head (h) = -70mmhg = -0.07 m hg

Acceleration due to gravity = 9.8 m/s²

Density of mercury = 13,600 kg/m³.

Next, we would determine the gauge pressure:

$P_{guage} = \rho gh\\\\P_{guage} = -13600 \times 9.8 \times 0.07\\\\P_{guage} = -9,329.6\;N/m^2$

Now, we can calculate the absolute pressure:

$P_{abs} = P_{atm} + P_{guage}\\\\P_{abs} = 1 \times 10^5 - 9329.6$

Absolute pressure = ‭90,670.4‬ N/m².

Two vertical parallel plates are spaced 0.01 ft apart. If the pressure decreases at a rate of 60 psf/ft in the vertical z-direct

Whitepunk [10]

Answer:

umax = 0.1259ft/s

Explanation:

Given:

•Distance between plates, B = 0.01ft

•Pressure difference decrease, $\frac{dp}{dz}=60ps/ft$

•Fluid viscosity, u = 10^-³lbf-s/ft²

Specific gravity, S = 0.80

Max velocity in the z-direction will be:

$u_max= [\frac{B^2y}{8u}]\frac{dh}{ds}$

$But h = \frac{P}{y}+z$

Substituting for h in the first equation, we have:

$\frac{d}{dz}[\frac{p}{y}+z]$

$\frac{dh}{dz}=\frac{1}{y}\frac{dp}{ds}+\frac{dz}{dz}$

$= \frac{1}{0.8*62.4}(-60)+1$

= -0.20192

Substituting dh/dz value in the first equation (umax), we have:

$umax = \frac{0.01^2(0.8*62.4)}{8*10^-^3}(-0.20192)$

umax = 0.1259ft/s
