A 78-percent efficient 12-hp pump is pumping water from a lake to a nearby pool at a rate of 1.5 ft3/s through a constant-diamet

fenix001 [56]

Answer:

irreversible head loss is 38.51 ft

mechanical power 6.55 hp

Explanation:

Given data:

Pump Power 12 hp = 8948.39 watt = 6600 lbs ft/sec

Q = 1.5 ft^3/s

Pump actually delivers $P' = \eta P = 0.78 \times 8948.39 = 6979.74 watt$

Power that water gains $= mgh = \rho \phi gh = r \phi h$

$P = 62.4 \times 1.5 \times 32 = 2995.2 lbs ft/sec$

hence Power lost = 6600 - 2995.2 3604.8 lbs ft/sec = 6.55 hp

head loss $hl = \frac{3604.8}{r \phi} = \frac{3604.8}{62.4 \times 1.5}$

hl = 38.51 ft

A differential amplifier is to have a voltage gain of 100. What will be the feedback resistance required if the input resistance

yuradex [85]

Answer:

required feedback resistance ( R2 ) = 100 k Ω

Explanation:

Given data :

Voltage gain = 100

input resistance ( R1 ) = 1 k ohms

calculate feedback resistance required

voltage gain of differential amplifier

$\frac{Vout}{V2 - V1 } = \frac{R2}{R1}$

= Voltage gain = R2/R1

= 100 = R2/1

hence required feedback resistance ( R2 ) = 100 k Ω
