Answer:

Option (d) MEP and IHP

Explanation:

MEP stands for Mean Effective Pressure and IHP stands for Indicated Horse Power

In engines (Internal Combustion), engine indicator is generally to indicate the indicate the changes in pressure inside the cylinder of an Internal Combustion Engine or IC engines. Once, Mean Effective Pressure of the engine is calculated it further helps to calculate the Horse power and both these quantities, i.e., MEP and IHP are displayed on the engine indicator.

These waveforms are applied to a gated D latch, which is initially RESET. Which of the areas identified on the Q waveform is inc
Andrej [43]

Question Completion with Options:

A) Area a B) Area b C) Area c D) Area d

Answer:

The incorrect waveform identified on the Q waveform is the:

C) Area c.

Explanation:

Area c is the incorrect waveform because its output is not correct.  The Q waveform indicates that the electrical forces project toward the negative pole of the lead axis.  A gated D latch is a flip flop latch with an additional control input, which determines when to change the state of the circuit. Most times, this control unit is a clock input or an enable input.

How much extra water does a 21.5 ft, 175-lb concrete canoe displace compared to an ultra-lightweight 38-lb Kevlar canoe of the s
pantera1 [17]

Answer:

The volume of the extra water is 2.195 ft^{3}

Solution:

As per the question:

Mass of the canoe, m_{c} = 175 lb + w

Height of the canoe, h = 21.5 ft

Mass of the kevlar canoe, m_{Kc} = 38 lb + w

Now, we know that, bouyant force equals the weight of the fluid displaced:

Now,

V\rho g = mg

V = \frac{m}{\rho}                                  (1)

where

V = volume

\rho = 62.41 lb/ft^{3} = density

m = mass

Now, for the canoe,

Using eqn (1):

V_{c} = \frac{m_{c} + w}{\rho}

V_{c} = \frac{175 + w}{62.41}

Similarly, for Kevlar canoe:

V_{Kc} = \frac{38 + w}{62.41}

Now, for the excess volume:

V = V_{c} - V_{Kc}

V = \frac{175 + w}{62.41} - \frac{38 + w}{62.41} = 2.195 ft^{3}

An oil reservoir has a average porosity of 20%, an area of 100 acres, and a av- erage thickness of 10 feet. The connate water sa
hram777 [196]

Answer:a) recovery factor = 53.3% ,bi) volume of oil per acre-ft = 11090.64bbl/acre-ft

bii) bulk volume of the reservoir in acre-ft = 1000 acre-ft

c) 62214.74 cubic feet

Explanation: a) recovery factor is the percentage amount of oil that can recovered from a reservoir, it is the oil produced divided by oil initially in place

Recovery factor= 1 - (Soi/1-Swi)

= 1 - (0.35/1-0.25)

= 0.533 × 100%

= 53.3%

bi) volume of oil which may be recovered per acre-ft = 7758.porosity.(1- Swi-Soi)

= 7758 x 0.2 x (1-0.25-0.35)

= 620.64 bbl/acre-ft

bii) bulk volume of the reservoir in acre-ft= Area x thickness

= 100 acres x 10 ft

= 1000 acre-ft

c) total volume of oil in cubic feet

since we have gotten volume as 1000 acre-ft we simply multiply it by the volume of oil gotten in answer bi)

= 1000 acre-ft x 620.64 bbl/ acre-ft

= 620640bbl

So we convert from barrel(bbl) to cubic feet, and 1 barrel is equal to 5.609 cubic feet, so to convert the answer from barrel to cubic feet we multiply the answer 620640 bbl by 5.609

= 620640 bbl x 5.609

= 3481580.711 cubic feet
