Answer:
W = 12.8 KW
Explanation:
given data:
mass flow rate = 0.2 kg/s
Engine recieve heat from ground water at 95 degree ( 368 K) and reject that heat to atmosphere at 20 degree (293K)
we know that maximum possible efficiency is given as
rate of heat transfer is given as
Maximuim power is given as
W = 0.2038 * 62.7
W = 12.8 KW
Answer:
c. an abrupt increase followed by a gradual decrease
Explanation:
At the headwater, the flow gradient starts high but then slowly decreases as the river moves downstream to its mouth.
Answer:
Explanation:
Products of oil in our everyday life:
(1) Petro-Chemical Feedstock: These are by product of Refining of Oil which it is used extensively to make PET bottles, Paints, Polyester Shirts, Pocket combs e.t.c
(2) Asphalt : Used extensively to make Motor Road, highways
(3) Plastics : we use plastics in our everyday life, this is also a product of Refining of crude oil e.g PVC, Telephone casing, Tapes e.t.c
(4) Lubricating Oil/Grease : This is another product from crude oil Fractional Distillation.
(5) Propane/ Cooking Gas: This is also a product from oil which is used in our everyday life for cooking, grilling etc.
5-6 feet is 60-72 inches and 8 feet is 96 inches
Answer:
The minimum mass flow rate will be "330 kg/s".
Explanation:
Given:
For steam,
For water,
They add energy efficiency as condenser becomes adiabatic, with total mass flow rate of minimal vapor,
⇒ 
On putting the estimated values, we get
⇒ 
⇒
