What are the common foodstuffs for guinea pigs?
What will be an ideal response?
Guinea pig pellets are available that contain all the nutrients needed. These pellets are hard and serve to wear
the teeth down.
Pellets that have high alfalfa content and dry alfalfa hay are suitable for young, growing guinea pigs and
pregnant females. Clover and grass hay pellets and dry clover and grass hays with low protein content are
more desirable for grown animals. It is important that hay not be moldy, musty, or dusty; moldy hay can be
fatal. The pellets and dry hay also help to wear the animal's teeth down.
Romaine lettuce, green leaf lettuce, carrots, apples, pears, turnips, beets, and cucumbers are also favorite
foods of guinea pigs. Iceberg lettuce should be avoided because it is less nutritious and may lead to diarrhea.
Wheat, corn, and oats are high-protein foods that can be added to the diet.

An insulated air compressor is to pressurize air from 100 kPa to 700 kPa. The air enters at 15°C, and exits at 250°C.
(a) Using your model of a compressor, plot the power required for this compressor for mass flow rates varying from 0.005 kg/s to 5 kg/s. (b) If the maximum power that can be supplied to the compressor via the current electrical system in use is 300 kW, determine the range of mass flow rates of compressed air that this compressor can produce. Given: P1 = 100 kPa; T1 = 15°C; T2 = 250°C; P2 = 700 kPa; Air (Take State 1 as the inlet, State 2 as the outlet.) Assume: Q?=0 (insulated). For a compressor, assume steady-state, steady-flow, single-inlet, single-outlet flow, with ?KE = ?PE = 0 What will be an ideal response?
A resistive load of 5 ? is connected to an ac source of 120 V (rms) through an SCR circuit.
a. If the SCR circuit consists of a single SCR, and if the triggering angle is adjusted to 30o, calculate the power consumption of the load. b. If the SCR circuit consists of two back-to-back SCRs, calculate the power consumption of the load assuming that the triggering angle is kept at 30o
