WEIGHT would be .032 kg * 9.81 m/s^2 = .31392 j
An iron–constantan thermocouple is to be used to measure temperatures between 0 and 400°C. What will be the non-linearity error as a percentage of the full-scale reading at 100°C if a linear relationship is assumed between e.m.f. and temperature? e.m.f. at 100°C = 5.268 mV, e.m.f. at 400°C = 21.846 mV
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.

An evacuated tank is filled with gas from a constant pressure line. Develop an expression relating the temperature of the gas in the tank to the temperature of the gas in the line. Assume the gas is ideal with constant heat capacities, and ignore heat transfer between the gas and the tank.
The temperature of the gas in the tank is the ratio of heat capacities times the temperature of gas in the constant pressure line.
What is temperature?It should be noted that temperature simply means the measure of hotness and coldness in a body
From the given information, H is the enthalpy of gas on the constant pressure line, m is the mass flow rate and U is the internal energy of gas.
Here, the temperature of the gas in the tank is the ratio of heat capacities times the temperature of gas in the constant pressure line.

Which of these items is least likely to cause an exhaust emission test failure as of a result of excessive nox emissions? a) poorflow through the egr system. b) spark plug hot range. c) defective fuel injector d) defective oxygen senor
The item that is least likely to cause an exhaust emission test failure as of a result of excessive nox emissions is; poorflow through the egr system.
What is an exhaust emission?Exhaust emissions simply means substances emitted into the atmosphere from the exhaust discharge nozzle of an aircraft or aircraft engine.
Now, when the test fails as a result of excessive nox emissions, we can say that high NOx emissions can occur when an engine's air-fuel mixture is too lean. Thus, we can conclude that the reason for exhaust emission test failure as of a result of excessive nox emissions is due to poorflow through the egr system.

Because of market demand the farmer will grow twice as many hectares of wheat as corn. He has allocated $6,375,000.00 for the cost of growing his crops. How many hectares of each crop should he plant?
The number of hectares of each crop he should plant are; 250 hectares of Corn, 500 hectares of Wheat and 450 hectares of soybeans
How to solve algebra word problem?
He grows corn, wheat and soya beans on the farm of 1200 hectares. Thus;
C + W + S = 12 ----(1)
It costs $45 per hectare to grow corn, $60 to grow wheat, and $50 to grow soybeans. Thus;
45C + 60W + 50S = 63750 -----(2)
He will grow twice as many hectares of wheat as corn. Thus;
W = 2C ------(3)
Put 2C for W in eq 1 and eq 2 to get;
C + 2C + S = 1200
3C + S = 1200 -----(4)
45C + 60(2C) + 50S = 63750
45C + 120C + 50S = 63750
165C + 50S = 63750 ------(5)

A 750-m section of river runs parallel to a channel 1,000 m away. an aquifer connecting the two has hydraulic conductivity equal to 7. 0 m/day and an average thickness of 10 m. the surface of the river is 5. 0 m higher than the surface of the channel. estimate the rate of seepage (qseepage) from the river to the channel
Given a 750 m section with distance of 1000m , The calculated rate of seepage from the river to the channel has been calculated to be 262.5 m³/day.
What is the rate of seepage?
This is the calculated rate that shows how water is infiltrated downward into the soil.
The formula is given as
[tex]Q = KA \frac{dh}{dl}[/tex]
A = Area = 750*10 = 7500m
dh = h₂-h₁
= 10 - 5 = 5m
dl = 1000m

An amount P is deposited now so that an equal annual amount of A1=2000 per year for the first 5 years, starting 1year after the deposit. And a different annual withdrawal of A2= 3000 per year for the following 3 years. Draw the cash flow diagram if i=8.5% per year.
Based on the amounts to be withdrawn over the years and the interest rate, the amount deposited now is $12,977.
How much is deposited now?This can be found as:
= (2,000 x Present value of annuity interest factor, 8.5%, 5 years) + (3,000 x Present value of annuity interest factor, 8.5%, 8 years) - (P/A, 8.5%, 5 years)
