What is the formula Nplan 33000 is equal to the?
Mechanical horsepower
| ≡ 33,000 ft·lbf/min | by definition | |
|---|---|---|
| = 550 × 0.3048 × 0.m⋅kgf/s | since | 1 ft ≡ 0.3048 m and 1 lb ≡ 0.kg |
| = kgf⋅m/s | ||
| = × 9.80665 kg⋅m2/s3 | since | g = 9.80665 m/s2 |
| = 745.699 W | since | 1 W ≡ 1 J/s = 1 N⋅m/s = 1 (kg⋅m/s2)⋅(m/s) |
What does the P stand for in the plank formula?
mean effective pressure
What does the N stand for in the plank formula?
In engineering class the formula for power was PLANk=HP. P=bmep brake mean effective pressure (average pressure for power stroke) L=stroke. A=piston area. N=revs/min.
How do you calculate IHP?
What is Horse Power? How to calculate & use it effectively?
- F.H.P = I.H.P – B.H.P.
- The relation between the BHP, Ps & kW is:
- 1 Hp = 1.01 PS = 0.70 kW.
- 1kW = 1.34 Hp = 1.4 PS.
- 1 PS = 0.98 Hp = 0.70 kW.
- Hp = Torque X RPM ÷ 5252.

How do you calculate the power of a 4 stroke engine?
Power in kW = (Pm LAN/n 100)/60 in bar where Pm = mean effective pressure L = length of the stroke in m A = area of the piston in m2 N = Rotational speed of engine RPM n= number of revolutions required to complete one engine cycle n= 1 (for two stroke engine) n= 2 (for four stroke engine) Thus we can see that for a …
What is the friction power?
Engine fuel consumption is influenced by friction between the various engine components. Engine friction power (FP) of a direct injection diesel engine is calculated from the measured value of in-cylinder pressure signals at various operating conditions. : Physical characteristics of both engine lubricants.
What is IP and BP in IC engine?
The brake power (briefly written as B.P.) of an IC Engine is the power available at the crankshaft. The brake power of an I.C. Note : The brake power (B.P.) of an engine is always less than the indicated power (I.P.) of an engine, because some power is lost in overcoming the engine friction (known as frictional power).
What is IP BP?
Drugs manufactured in India have to be labelled with the mandatory non-proprietary drug name with the suffix I.P. This is similar to the B.P. suffix for British Pharmacopoeia and the U.S.P. suffix for the United States Pharmacopeia.
What is IP IC engine?
The indicated power of an IC engine (briefly written as I.P.) is the power actually developed by the engine cylinder.
What is IP BP FP?
ip − fp = bp Where ip = indicated power fp = friction loss bp = break power brake power can also be expressed as: bp = ( bmep ) LAnK 60 × 1000 equation 1: brake power equation Where: bp = brake power (Kw) Bmep = break mean effective pressure (kN/m ) L = length of stroke(m) A = cross-sectional area of piston (m ) n = …
What is the relation among BP IP and FP?
The IP is thus IP=BP+FP. Thus, the total IP for the engine is IP = IP1 + IP2 + IP3 + and with the BP calculated ini- tially, the FP and ηm will easily be obtained.
How do scavenging works What is the principle?
Scavenging is the removal of exhaust gases by blowing in fresh air. Charging is the filling of the engine cylinder with a supply or charge of fresh air ready for compression. With supercharging a large mass of air is supplied to the cylinder by blowing it in under pressure.
What are the types of scavenging?
Abstract: The process of simultaneously purging exhaust gas and filling the cylinder with fresh charge for a new cycle is referred to as scavenging. The main scavenging methods are cross scavenging, loop scavenging and uniflow scavenging.
How scavenging is done?
Scavenging is the process of replacing the exhaust gas in a cylinder of an internal combustion engine with the fresh air/fuel mixture (or fresh air, in the case of direct-injection engines) for the next cycle.
What does scavenging mean?
1a(1) : to remove (dirt, refuse, etc.) from an area. (2) : to clean away dirt or refuse from : cleanse scavenge a street. b : to feed on (carrion or refuse) 2a : to remove (burned gases) from the cylinder of an internal combustion engine after a working stroke.
Why scavenging is required?
Scavenging is the process of removing exhaust gases from the cylinder after combustion and replenishing the cylinder with fresh air. Efficient scavenging is necessary for good combustion of fuel inside the engine cylinder. The passage of scavenge air will also assist cooling of the cylinder, piston and valves.
What is meant by perfect scavenging?
(1)Based on Theoretical process: (A)Perfect Scavenging: •Ideally, the fresh fuel-air mixture should remain separated from the residual combustion products w.r.t both mass and heat transfer during the scavenging process.
What is scavenging and its types?
The process of admitting air and expelling exhaust gas is known as scavenging. The three main types of scavenging for two stroke engines are cross flow, uniflow and loop flow.
What is cross flow scavenging?
Cross Flow Scavenging is the gas exchange process in which the charge air passes is directed upwards, passing under the cylinder cover and down the opposite side, expelling exhaust gas through exhaust ports on that side. This system is obsolete now.
What is scavenge efficiency?
Scavenge efficiency can be defined as the ratio of the volume of air in the cylinder at the start of the compression to the volume swept by the piston from the top edge of the ports to the top of the strokes.
How do you increase volumetric efficiency?
Volumetric efficiency can be improved in a number of ways, most effectively this can be achieved by compressing the induction charge (forced induction) or by aggressive cam phasing in naturally aspirated engines as seen in racing applications. In the case of forced induction volumetric efficiency can exceed 100%.
What is fuel compression?
The compression ratio is the ratio of the volume of the cylinder and the combustion chamber when the piston is at the bottom, and the volume of the combustion chamber when the piston is at the top. When the air is compressed, you get a more powerful explosion from the air-fuel mixture, and more of the fuel gets used.
