Answer:

Theoretically impossible

Explanation:

Given that:

The mass flow rate = 60 lbm/min

The differential pressure = 200 inches

The flow rate Q is can be expressed by the formula:

Q = K.A\sqrt{2g \Delta h}

where;

K = Discharge coefficient

A = area

Δh = Head drop

g = gravity

From the given parameter, the area is unknown.

Therefore, the flow coefficient of the meter will be theoretically impossible to be determined.

hammer [34]

Answer:

A) i) 984.32 sec

ii) 272.497° C

B) It has an advantage

C) attached below

Explanation:

Given data :

P = 2700 Kg/m^3

c = 950 J/kg*k

k = 240 W/m*K

Temp at which gas enters the storage unit  = 300° C

Ti ( initial temp of sphere ) = 25°C

convection heat transfer coefficient ( h ) = 75 W/m^2*k

<u>A) Determine how long it takes a sphere near the inlet of the system to accumulate 90% of the maximum possible energy and the corresponding temperature at the center of sphere</u>

First step determine the Biot Number

characteristic length( Lc ) = ro / 3 = 0.0375 / 3 = 0.0125

Biot number ( Bi ) = hLc / k = (75)*(0.0125) / 40 = 3.906*10^-3

Given that the value of the Biot number is less than 0.01 we will apply the lumped capacitance method

attached below is a detailed solution of the given problem

<u>B) The physical properties are copper</u>

Pcu = 8900kg/m^3)

Cp.cu = 380 J/kg.k

It has an advantage over Aluminum

C<u>) Determine how long it takes a sphere near the inlet of the system to accumulate 90% of the maximum possible energy and the corresponding temperature at the center of sphere</u>

Given that:

P = 2200 Kg/m^3

c = 840 J/kg*k

k = 1.4 W/m*K

An iron–constantan thermocouple is to be used to measure temperatures between 0 and 400°C. What will be the non-linearity error
hram777 [196]

Answer:

  -0.89%

Explanation:

Assuming a proportional relationship between EMF and Celsius temperature, the measured value of EMF at 100 °C will be interpreted as a temperature of ...

  T/5.268 = 400/21.846

  T = 5.268(400/21.846) ≈ 96.457 . . . . °C

The error as a fraction of full scale is ...

  (96.457 -100)/400 × 100% ≈ -0.886%

The error at 100 °C is about -0.89% of full scale.
