Answer

given,

oil barrel weight  = 1.5 k N = 1500 N

weight of the barrel = 110 N

Assuming volume of barrel = 0.159 m³

weight of oil = 1500-110

                     = 1390 N

specific\ weight = \dfrac{weight}{volume}

specific\ weight = \dfrac{1390}{0.159}

            = 8742.14 N/m³

mass = \dfrac{weight}{g}

mass = \dfrac{1390}{9.8}

              = 141.84 kg

density = \dfrac{mass}{volume}

density = \dfrac{141.84}{0.159}

                    = 892.05 kg/m³

Specific\ gravity = \dfrac{density\ of\ oil}{density\ of\ water}

Specific\ gravity = \dfrac{892.05}{1000}

                    = 0.892

gulaghasi [49]

Answer:

The given blanks can be filled as given below

Voltmeter must be connected in parallel

Explanation:

A voltmeter is connected in parallel to measure the voltage drop across a resistor this is because in parallel connection, current is divided in each parallel branch and voltage remains same in parallel connections.

Therefore, in order to measure the same voltage across the voltmeter as that of the voltage drop across resistor, voltmeter must be connected in parallel.

Steam enters an adiabatic turbine at 10 MPa and 500°C and leaves at 10 kPa with a quality of 90 percent. Neglecting the changes
Anna35 [415]

Answer:

The mass flow rate of steam m=5.4 Kg/s

Explanation:

Given:

  At the inlet of turbine P=10 MPa  ,T=500 C

 AT the exit of turbine  P=10 KPa   ,x=0.9

 Required power=5 MW

From steam table

<u> At 10 MPa and 500 C:</u>

  h=3374 KJ/Kg  ,s=6.59 KJ/Kg-K  (Super heated steam table)

<u>At 10 KPa:</u>

h_g=2675.1 KJ/Kg, h_f=417.51  KJ/Kg

s_g= 7.3  KJ/Kg-K                ,s_f=1.3   KJ/Kg-K

So enthalpy of steam at the exit of turbine

h= h_f+x(h_g- h_f)

Now by putting the values

h= 417.51+0.9(2675.1- 417.51) KJ/Kg

h=2449.34  KJ/Kg

Lets take m is the mass flow rate of steam

So 5\times 10^3=m\times (3374-2449.34)

m=5.4 Kg/s

So the mass flow rate of steam m=5.4 Kg/s
