A cylinder contains 480 cm3 of loose dry sand which weighs 820 g. Under a static load of 200 kPa the volume is reduced 1%, and t

hen by vibration it is reduced 10% of the original volume. Assume the solid density of sand grains is 2.65 Mg/m3 . Compute the void ratio, porosity, dry density, and total density corresponding to each of the following cases:__________.(a) Loose sand. (b) Under static load. (c) Vibrated and loaded sand.

Answer:

a.

b.

c.

Explanation:

a. void  ratio is provided by the formula: e = \frac{V_{p} }{V_{s}  }

   where , V_{p} = volume of voids

                V_{s} = volume of solid grains

for loose sand, the void space = \frac{480}{480}

                                                   = 1

b. void ratio after static load = 0.1/(480)/ (480)

                                               = 0.1

c. void ratio after vibration = [480- ( 0.1 * 480) ]/ 480

                                             = 0.9

Rashid [163]

The heat transferred to and the work produced by the steam during this process  is 13781.618 kJ/kg

<h3>​How to calcultae the heat?</h3>

The Net Change in Enthalpy will be:

= m ( h2 - h1 ) = 11.216 ( 1755.405 - 566.78 ) = 13331.618 kJ/kg

Work Done (Area Under PV curve) = 1/2 x (P1 + P2) x ( V1 - V2)

= 1/2 x ( 75 + 225) x (5 - 2)

W = 450 KJ

From the First Law of Thermodynamics, Q = U + W

So, Heat Transfer = Change in Internal Energy + Work Done

= 13331.618 + 450

Q = 13781.618 kJ/kg
