Air at T1 = 32°C, p1 = 1 bar, 50% relative humidity enters an insulated chamber operating at steady state with a mass flow rate
RUDIKE [14]

Answer:

4.5kg/min

Explanation:

Given parameters

T_1 = 32^0 C,  m_1 = 3 kg/min, T_2 = 7^0 C ,T_3 = 17^0

if we take  

The mass flow rate of the second stream = m_2(kg/min)

The mass flow rate of mixed exit stream = m_3 (kg/min)

Now from mass conservation

m_3 = m_2 + m_1

m_3 = m_2 + 3 (kg/min)

The temperature of the mixed exit stream given as

T_3m_3 = T_2m_2 +T_1m_1\\\\17 ( 3 + m_2) = 7 \times m_2 + 32 \times 3\\\\51 + 17 m_2 = 7 m_2 + 96\\\\10 m_2 = 96 - 51\\\\m_2 = 4.5 kg/min\\\\\\\\

Therefore the mass flow rate of second stream will be 4.5 kg/min.

A beam has a rectangular cross section that is 5 inches wide and 1.5 inches tall. The supports are 60 inches apart and with a 12
nydimaria [60]

Answer:

The value of Modulus of elasticity E = 85.33 × 10^{6} \frac{lbm}{in^{2} }

Beam deflection is = 0.15 in

Explanation:

Given data

width = 5 in

Length = 60 in

Mass of the person = 125 lb

Load = 125 × 32 = 4000\frac{ft lbm}{s^{2} }

We know that moment of inertia is given as

I = \frac{bt^{3} }{12}

I = \frac{5 (1.5^{3} )}{12}

I = 1.40625 in^{4}

Deflection = 0.15 in

We know that deflection of the beam in this case is given as

Δ = \frac{PL^{3} }{48EI}

0.15 = \frac{4000(60)^{3} }{48 E (1.40625)}

E = 85.33 × 10^{6} \frac{lbm}{in^{2} }

This is the value of Modulus of elasticity.

Beam deflection is = 0.15 in

How have railways developed to date?
frozen [14]

Railways development is constantly growing as it is changing from diesel or fuel powered railways to electric powered railways.

<h3>How was railways developed?</h3>

The first working railway steam locomotive was known to be created by the United Kingdom in the year 1804 through  man known as Richard Trevithick who was a British engineer.

Note therefore that railway is changing from  high-pressure steam to electric powered railways.

Iron filings and a bar magnet are shown in the image below. Which of the following best explains the arrangement and position of
Alla [95]

The statement that best explains the arrangement and position of the iron filings is A. the magnetic field around the magnet

<h2 /><h2>Magnetic field around a magnet</h2>

When we have a magnet, there is a magnetic field around the region of the magnet where the effect of the magnetic force of the magnet is felt. The magnet has both a North pole and a South pole.

<h3 /><h3>Magnetic field lines</h3>
  • Magnetic field lines which show the direction of the magnetic field emanate from the North pole and terminate at the South pole of the magnet.
  • When iron filings are brought into the region of a magnet to surround it, the iron filings align in the direction of the magnetic field around the magnet since they are magnetic.

So, the statement that best explains the arrangement and position of the iron filings is A. the magnetic field around the magnet
