Question

(İ)An area was measured on a plan by a ruler as 180 mm and 160
mm. Calculate the ground area in m^{2} , if the scale is
1:250.

(ii) An area of 12500 cm^{2} was measured on a plan
using the planimeter. Given that the plan scale 1:250, calculate
the ground area hectares. (5 pts)

Answer #1

An
area was measured on a plan by a ruler as 180 mm and 160 mm.
Calculate the ground area in m2 , if the scale is 1:250.

The front wall of an old jewellery store has an area of 20 m2
and is constructed of 200 mm of concrete and 250 mm of polystyrene.
The wall contains a large window of 5 m x 2 m of 50 mm thick glass.
The inside temperature is 21°C and the outside temperature is 3°C.
Calculate: (i) the rate of flow of heat through the glass, and (ii)
the total rate of heat transfer through the wall and window. Note:...

Question 2. Answer all parts of this question a) A shell and
tube heat exchanger is to heat 10,000 kg h–1 of water from 16 to
84°C using hot oil entering at 160°C and leaving at 92°C. The oil
will flow through the shell of the heat exchanger. The water will
flow through 11 brass tubes of 22.9 mm inside diameter and 25.4 mm
outside diameter, with thermal conductivity 137 W m–1 K–1, with
each tube making two passes through...

1) A nozzle is a device for increasing the velocity of a
steadily flowing stream of fluid. At the inlet to a certain nozzle
the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s.
At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle
is horizontal and there is negligible heat loss from
it.
(i) Find the velocity at the nozzle exit.
(ii) If the inlet area is 0.1 m2 and specific volume...

Barry is currently obese and would like to lose weight. Barry is
watching television and sees two different infomercials about
weight loss products. The first infomercial is for a weight loss
"supplement, called ICBINM (I Can't Believe It's Not Meth), the
customer takes daily to "increase metabolism and energy". The
infomercial for ICBINM shows 3 different verified customers who
used the product and lost a lot of weight. The second infomercial
is for a weight loss "program", called TNKD (The...

I have provided the information for the lab below. I want to see
the chemical reactions that take place during each step of the
experiment. So in the procedures when a chemical was added i would
like to see what the products and byproducts that were formed. I
also want to see one over all reaction for this experiment to just
get an overview of what exactly is happening during the experiment.
Thank you:)
